Do you often experience pain in the upper part of your arm or leg? It could be Extensor Tendinitis!

Sometimes you may have felt a slight pain, like a tingling sensation, coming from the top of your arm or leg. Sometimes you may feel that this pain increases when you extend your fingers or lift your leg. This is not just a muscle twitch, but it could be due to a condition called 'extensor tendinitis' that we are talking about today.

What is Extensor Tendinitis?

Simply put, extensor tendonitis is a type of tendinitis that affects the tendons on the back of your arms (not the other side, but the other side) and the tops of your legs. Okay, now you're probably wondering what a tendon is and what tendonitis is, right?

Tendons are like strong, flexible cords. They connect our muscles to our bones . So when we move our arms or legs, these tendons help transfer the force of the muscles to the bones and make them move. Extensor tendons are a special type of tendon. In the hands, these help you spread your fingers and straighten them. In the legs, they help you raise your toes and bend your ankles.

'Tendinitis' refers to inflammation, or simply swelling, of this tendon tissue. Just like when you get a small injury, it becomes swollen and red. So, 'extensor tendonitis' refers to swelling, or inflammation, of this extensor tendon on the top of your arm or leg.

This condition is usually caused by repetitive movements that put too much strain on the tendons, causing them to become damaged over time. This can be caused by the way you work, play, or do certain activities frequently.

Who is more likely to develop Extensor Tendinitis?

This condition can actually happen to anyone. However, some people are more likely to develop it. This is especially true if you use your arms or legs in the same way all the time, whether it's because of your job or a hobby you do.

For example, someone who types on a computer all day can develop this condition in the tendons that extend the fingers of the hand. Or, someone who works standing all day, for example, someone who works in a shop, a teacher, can have this condition affect the tendons on the top of the leg. People who do carpentry, painting, gardening (when hoeing, pulling weeds), and people who wash clothes by hand with a stick are also at risk.

Additionally, people with certain health conditions are more likely to develop extensor tendonitis:

• People with immune system diseases , for example, conditions like `(Rheumatoid Arthritis)`.
• People with certain types of arthritis , for example `(Gout)`.
• People with leg problems, like osteoarthritis.
• People with flat feet or high arches.

People over the age of 40 and those with generally stiff tendons (lack of flexibility) are more likely to develop this condition. It has also been found that smokers are at a higher risk of developing tendinitis .

How common is this condition?

The condition 'tendinitis' is actually very common. Among them, 'extensor tendinitis' is especially common among those who work or play sports and use their arms and legs frequently, as mentioned earlier.

How will this affect my body?

When your tendons are swollen and painful, it can be painful and difficult to perform everyday tasks when you use that limb. Imagine, if you have difficulty extending your fingers, how difficult is it to write or hold something? If the top of your leg hurts, how difficult is it to walk or climb stairs?

As we mentioned earlier, tendons are what connect muscles to bones. So when these 'extensor tendons' become inflamed, they don't move as smoothly as they should. That's why the pain comes, and it becomes difficult to move the limb. Especially, the pain can increase when you do the activity that caused the tendinitis.

What is the difference between Extensor Tendinitis and Stress Fractures?

The symptoms of both can sometimes be similar. You may experience pain in either the arm or the leg. Both can be caused by repetitive motions (overuse). However, the actual damage to both is to different parts of the body.

If you have extensor tendinitis, you've damaged an extensor tendon, which is the cord-like tissue that runs under the skin on the top of your leg or the back of your hand.

However, a ``Stress Fracture`` is a small crack or break in a bone . To be precise, in the case of the hand, in the bones called ``metacarpals`` that give shape to the hand, and in the case of the foot, in the ``metatarsals`` that form the arch of the foot and connect the back of the foot to the toes. This does not happen all at once, but when you continue to make the same movements, or when you play sports vigorously, the bone swells from the inside and over time, this small crack occurs.

Therefore, regardless of the cause, if you experience symptoms such as pain or swelling in your arm or leg, it is best to see a doctor immediately for an examination.

What are the symptoms of Extensor Tendinitis?

In this situation, you may experience symptoms such as:

• Pain: You may feel pain along the tendon or in the surrounding area.
• Pain increases when using the arm or leg: This pain may increase when doing something or walking.
• Stiffness: You may feel stiffness when you first wake up in the morning or when you try to use your arm/leg after not moving for a while.
• Swelling: The area where the pain occurs may be swollen.
• Color change or warmth: The area where the tendon is located may become red or feel warmer to the touch than other areas.

Let's also learn about the Extensor Tendon Zones.

Doctors may sometimes talk about 'zones' on your arm or leg. These are like the boundaries of a map. They divide your arm or leg into different parts and use these zones to help you identify and explain exactly where you have a problem. There are usually nine zones on the arms and four zones on the legs. This helps doctors plan treatment.

What are the causes of Extensor Tendinitis?

The main reason for this is that you keep using the same movements of your arms or legs . Over time, the normal stress on these extensor tendons increases, and they start to get damaged. This damage causes the tendons to swell (become inflamed). This swelling causes pain, and the tendons cannot move smoothly.

Here are some activities that can cause extensor tendonitis:

• Jobs that require standing all day: such as store employees and security guards.
• Gardening or landscaping: Things like hoeing, weeding, etc.
• Loud rubbing work: like scrubbing the floor, scrubbing dishes.
• Carpentry, painting.
• Sports injuries: Especially when using incorrect techniques.
• If you have hands, you can type continuously on a keyboard.
• In the case of feet, tight shoes, shoes that don't fit properly, and sometimes tying the shoelaces too tightly can also be a cause.
• This can also happen to new mothers . This is because they are constantly lifting their baby and staying in the same position while breastfeeding, which can cause some of the tendons in the wrist area to become strained.

In addition to these, if you suddenly twist an arm or leg – think of when you slip and fall and catch your hand, or when you trip and twist your leg – extensor tendinitis can also occur. But it's a little less common.

How is Extensor Tendinitis diagnosed?

When you see a doctor, the first thing he/she will do is ask you about your symptoms and examine your arm or leg (physical exam).

They may palpate your arm or leg to see if there are any swollen or painful areas. They may also ask you to perform certain movements to check your arm/leg's range of motion, strength, and pain intensity.

Sometimes, if the doctor suspects a torn tendon or other damage to the inside of the arm/leg, they may also order imaging tests like these:

• X-rays: To see if there is a problem with the bones.
• Musculoskeletal Ultrasound (MSK-US): This is very good for looking at soft tissues like tendons and muscles.
• CT scan or MRI scan: These are used if a clearer, more detailed picture is needed.

How is Extensor Tendinitis treated?

In most cases, this condition can be relieved with home remedies and over-the-counter painkillers.

Mainly, you should follow the 'RICE' method :

• R - Rest: Avoid activities that have damaged the tendons. Do not put excessive weight on the arm/leg until it heals.
• I - Ice: Apply an ice pack to the painful area about four times a day, for 15 minutes at a time. Do not apply the ice directly to the skin, wrap it in a cloth and apply it.
• C - Compression: To reduce swelling, you can wrap the painful area tightly with an elastic bandage. But don't wrap it so tightly that it cuts off blood flow.
• E - Elevation: Keep your arm or leg elevated above your heart whenever possible. This will help reduce swelling.

"Remember, this RICE method is like first aid. If the pain doesn't subside, see a doctor."

You can take painkillers called ``NSAIDs'' , such as aspirin or ibuprofen, to reduce pain and swelling. However, it is best to consult a doctor before taking these medications continuously for more than 10 days.

If your symptoms don't improve after a few weeks, your doctor may start additional treatments, such as:

• Corticosteroid injections: These are injections that are injected directly into the painful tendon. They reduce swelling and provide quick relief from pain. However, this is not a good idea to do regularly.
• Physical therapy: A physical therapist will teach you exercises and stretches to strengthen the muscles around the tendon and increase flexibility. This can help reduce symptoms and prevent the condition from recurring.

Surgery is rarely necessary for extensor tendonitis. Doctors only consider surgery if all other treatments have failed.

How long does it take to recover from this condition?

How quickly you recover depends on how much damage your tendons are doing and how well you rest them. Many people start to feel relief as soon as they rest their arm/leg and avoid the activities that damaged their tendons.

It can take anywhere from a few weeks to a few months for the tendon to fully heal. Talk to your doctor about the recovery time based on your condition.

Can Extensor Tendinitis be prevented?

Yes, this can be largely prevented. Here are some things to keep in mind:

When playing sports or engaging in other physical activities:

• Wear proper safety equipment.
• If you have pain in your arm or leg, don't do things like 'play through the pain'.
• After a good workout, give your body time to rest and recover.
• Before playing sports or exercising, warm up your body thoroughly, do exercises and stretches.
• Do cool down exercises and stretches after playing sports or exercising.
• If you feel pain in your tendons at the end of the day, see if you can wear wrist sleeves or ankle sleeves while working or exercising.

Follow these general safety tips to avoid accidents:

• Keep your home and workplace tidy by removing clutter and clutter that could cause you to trip.
• When reaching for something high, always use a suitable tool, such as a ladder. Never climb on chairs, tables, or counters.
• If you have difficulty walking or are more likely to fall, use your cane or walker.
• When choosing shoes, choose comfortable shoes that don't constrict your feet. Don't tie the laces too tightly.

What can I expect if I have Extensor Tendinitis?

You can expect a full recovery from this condition. This is a temporary condition. With proper treatment and rest, it will not have any long-term impact on your health, your work, or the activities you enjoy.

Will I have to take time off work or school if I have Extensor Tendinitis?

If you can do your job or schoolwork without putting too much strain on your arm or leg, you won't need to take time off until the tendon heals.

However, if your extensor tendonitis is caused by your job or a hobby, you will need to stay away from those activities for a while until you recover.

Can I walk or run with Extensor Tendinitis?

Many people can walk and move around even with extensor tendonitis in their legs. But be sure to give your body time to heal after walking and moving around.

Always consult a doctor before resuming physical activities like running or exercising. Doing the same activity that injured your tendon—especially if it caused your tendinitis—can worsen your symptoms. It can also cause further damage to the tendon, leading to a more serious condition like a torn tendon.

What time should I see a doctor?

If your symptoms, such as pain and swelling, do not subside within a few days, if they get worse, or if you are unable to move your arm/leg normally, see a doctor.

When should I go to an Emergency Treatment Unit (ETU) ?

If you have any of these symptoms, go to an emergency room immediately:

• Very severe pain.
• If the swelling is getting worse.
• If there is discoloration (like blue or purple).
• If you can't move your arm/leg at all.

What questions should I ask my doctor?

When you see your doctor, you can ask questions like these:

• Do I have extensor tendonitis or another disorder?
• Which tendons are damaged?
• How long will it take to heal?
• What activities should I avoid and for how long?
• What exercises can I do at home?

Extensor tendonitis is a painful condition that can make it difficult to function normally throughout the day. However, if you give your body the time it needs to heal, you can prevent a more serious problem from developing.

If this is due to an injury you sustained at work, talk to your doctor about what relief and facilities you can receive until you recover.

Take-Home Message
