Imagine if you were just sitting there and suddenly, for no apparent reason, you felt an unbearable pain in your shoulder. Sometimes this pain starts in the shoulder and travels down the arm. Even though the pain subsides after a few days, the arm feels numb and weak. This is the main symptom of a rare condition called Parsonage-Turner Syndrome, which we are talking about today. It usually affects only one side of the body.
What is Passanage-Turner Syndrome (PTS)?
Simply put, it is a disease of the nervous system, a neurological disorder. Your doctor may use other names for it. For example, they may call it 'brachial neuritis' or 'neurologic amyotrophy'.
In this disease, there is damage to the nerve network in our body called the 'brachial plexus'. Now you may be wondering what this brachial plexus is. That is, a collection of nerves that runs from our back through our neck, from our armpits down our arms. This nerve network controls the movements and sensations of our shoulders and arms. So when this is damaged, the pain and weakness mentioned earlier occur.
What causes this situation?
In fact, even doctors have not been able to find a specific cause for this yet. Most of the time, this condition occurs without any cause being found. However, it has been found that these symptoms can appear after certain events. Let's see what they are.
| Possible causes | A simple explanation |
|---|---|
| Viral or bacterial infections | It can occur after a common infection, such as a cold or flu. Some people who have contracted COVID-19 have also been reported to have this condition. |
| Surgery | There is a possibility of it occurring after any type of surgery. |
| Giving birth to a child | This can occur in some women even after giving birth. |
| Medical tests | After things like a spinal tap. |
| Other reasons | Strenuous exercise, injury, cancer cells, autoimmune conditions, and vaccinations (very rare). |
Is there a link between vaccines and PTS?
This is a common problem for many people. There have been reports of a small number of people developing this condition after receiving some flu and COVID-19 vaccines. For example, a French health agency reported that a small number of people who received the Pfizer or Moderna vaccines had PTS.
But you have to understand that this is very, very rare . It has not yet been clearly proven that a vaccine causes PTS. The protection provided by getting a vaccine far outweighs this very rare risk.
What are the symptoms of this?
Symptoms of PTS can vary from person to person. The location of the pain , its severity, and how long the weakness lasts vary from person to person.
It usually starts with a sudden, severe pain in the shoulder and upper arm. The pain can be stabbing, burning, nauseous , or sharp. The pain can last for hours, days, or even weeks. It gets worse when you move. After a while, the severe pain subsides, and muscle weakness begins to appear. You may feel like your arm is going numb, and you may not be able to lift anything.
| Main symptoms | Other possible symptoms |
|---|---|
| Severe, sudden shoulder/arm pain | Partially dislocated shoulder |
| Muscle weakness with pain relief | Shrinkage/wasting (atrophy) of the affected muscles |
| Decreased reflexes | Difficulty breathing (very rare) |
| Loss of sensation in the arm/shoulder | Unusual sweating |
| Red, purple, or blotchy skin on the hands and swelling |
How does a doctor diagnose this?
When you report these symptoms, your doctor will first examine you carefully, especially checking the strength, reflexes, and sensation of your shoulder and arm muscles. Then, they may order a few tests to confirm the diagnosis.
- Nerve Conduction Studies : This tests how well messages are traveling through one of your nerves to the brain.
- Electromyography (EMG): This involves inserting a very thin needle into a muscle and measuring its electrical activity. This can give a good idea of the health of the muscle and the nerves that control it.
- MRI scan: This is a painless test that uses magnets and radio waves to make clear pictures of the inside of your body, especially the nerves and muscles.
- X-ray : This is mainly used to check the condition of the bones. This helps to determine if the pain is due to another cause.
What are the treatments for this?
If your doctor confirms that you have this condition, you should work with him or her to manage your symptoms. The main goal is to reduce pain and regain muscle strength.
The following can be used as treatments:
- Painkillers: The doctor will prescribe medication to control the severe pain in the initial stages.
- Physical and Occupational Therapy: This is very important . These treatments are essential to restore muscle strength and range of motion in the hand.
- TENS therapy: This uses low-voltage electrical pulses to try to relieve nerve pain.
- Cold or hot compresses: Applying cold packs or heat pads to the painful area may provide some relief.
- Surgery: Very rarely, if a nerve is pinched or damaged, surgery may be necessary.
Will this condition be completely cured?
Many people can recover with treatment. But it takes time. It can take 2 to 3 years to fully regain strength and function in the hand. Therefore, it is very important to be patient with treatment . Treatment at a rehabilitation center can quickly relieve symptoms. Surprisingly, some people recover without any treatment.
This disease is not life-threatening (fatal). However, if not treated properly, it can lead to some kind of disability. Therefore, it is very important to follow medical advice.
