Are you also experiencing unbearable itching and bumps on your skin? Let's learn about (Prurigo Nodularis)!

Do you have hard, raised bumps on your skin that you can't stand? Is the itching worse at night? Sometimes, these bumps can become infected, bleed, and eventually become scabs. If you've experienced this, you may have a skin condition called Prurigo Nodularis (PN) . Let's talk about it in detail and simply today.

What is Prurigo Nodularis?

Simply put, it is a skin condition. The main symptom is hard, raised bumps on the skin. These bumps are often covered in dry, crusty skin. They can also be very itchy , especially at night. You may have just a few of these bumps, or you may have many in one area.

Although these bumps can appear anywhere on the body, they are most commonly seen on:

• Abdomen (stomach area)
• Hands
• Legs
• Skull (skull)
• Shoulders
• Upper back

The most important thing is that this condition is chronic . This means that it can last for a long time, sometimes getting better and then recurring. Therefore, it is something that requires a little patience and treatment.

Who is most likely to develop this condition?

Actually, anyone can develop `(Prurigo Nodularis)`. However, some people are more prone to developing it. For example:

• It is common among African Americans in countries like America.
• It is usually seen more often among adults between the ages of 40 and 69 .
• It also seems to be somewhat prevalent among women .

Also, if you have certain skin conditions, your risk of developing `(Prurigo Nodularis)` may increase.

People at higher risk for skin diseases

People with these skin conditions are at higher risk:

• `(Bullous pemphigoid)` (a skin disease that causes blisters)
• `(Cutaneous T-cell lymphoma)` (a type of cancer that occurs in the skin)
• Eczema (Eczema / Atopic dermatitis)
• Keratoacanthomas (a type of skin tumor caused by sun exposure)
• Lichen planus (a skin and mucous membrane disease)
• Other types of prurigo (other skin diseases caused by itching)
• Psoriasis
• Excessive dryness of the skin (Xerosis cutis)

People at higher risk due to other health conditions

Not only skin diseases, but also some other health conditions increase the risk of developing ``Prurigo Nodularis''.

• `(Cancer)` (Cancer)
• Some bacterial, viral, and parasitic infections
• Diabetes
• Gout
• `(HIV - Human Immunodeficiency Virus)` infection
• Iron deficiency (anemia)
• Kidney failure or chronic kidney disease
• Liver disease
• Lupus (a disease of the connective tissue)
• Nervous system disorders
• Some mental health conditions, for example, psychogenic pruritus or Obsessive-Compulsive Disorder (OCD).
• Thyroid disease

Important: If you have any of these conditions, it does not mean that you will definitely develop `(Prurigo Nodularis)`. However, keep in mind that the risk is relatively high.

How common is Prurigo Nodularis?

In the United States, statistics show that about 72 out of 100,000 people have this disease. However, experts believe that the actual number of people with this condition may be much higher. Because it sometimes occurs together with other skin diseases, there are times when doctors are unable to accurately diagnose it.

What are the symptoms of this?

There are several main symptoms of `(Prurigo Nodularis)`. Let's see what they are:

• Raised bumps on the skin : These are usually covered with a thick, dry crust. The bumps may be the same color as your skin, or they may be light pink, dark red, brown, or black.
• The size and depth of the bumps can vary : Some bumps can affect both the epidermis, the top layer of the skin, and the dermis, the middle layer.
• Intense itching : This is the main and most uncomfortable symptom of this disease. Some people may also experience a burning or stinging sensation in addition to the itching.

Here are the types of lumps:

These lumps can be divided into three main types:

• Nodules : These are larger than 1 centimeter and have penetrated the epidermis of the skin.
• Papules : These are smaller than 1 centimeter and are only on the surface of the skin.
• Plaques : These are shallow, scaly lesions that are larger than 1 cm but do not extend below the skin's surface.

What causes Prurigo Nodularis?

First of all, this is not a contagious disease . That is, it is not spread from one person to another through contact.

Although the exact cause of this has not yet been determined, it is believed that some factors play a role:

• Overactivity of nerve cells or immune cells in the skin.
• These bumps can develop from the intense itching caused by other skin conditions, from constant scratching and skin damage. To be precise, an itch-scratch cycle occurs. Scratching causes bumps, and when the bumps appear, they cause more scratching.
• Certain medications, for example, some chemotherapy drugs used for cancer, can also cause prurigo nodularis.

How is this diagnosed?

If you have these symptoms, you should definitely see a dermatologist. He or she will examine your skin. They will look at the size, color, and location of the bumps. They will also ask you how much you scratch and when the itching gets worse.

Important: Be sure to tell your doctor about any other skin conditions, health conditions, and allergies you have. This information will help differentiate `(Prurigo Nodularis)` from other conditions.

What tests are performed?

Typically, tests like these can be done:

• Dermoscopy : In this procedure, the doctor examines your skin with a handheld, lighted magnifying device (dermoscope). This allows the doctor to magnify the skin lesions without having to cut the skin.
• Blood and urine tests : Complete blood count (CBC), basic metabolic panel (BMP), and urinalysis can help detect liver, thyroid, or kidney problems, as we discussed earlier, which can also cause this.
• Skin biopsy : In this, a small piece of skin (including the top layer of skin - the epidermis and the middle layer - the dermis) is taken from the affected area and examined under a microscope. The area is numbed before this is done. This can be used to check for abnormal cells and other signs of disease.

What are the treatments?

The best thing is, there are treatments for `(Prurigo Nodularis)`. However, since it is a chronic condition, treatment can take some time and requires patience.

Basic treatment

The following treatments are usually used for mild cases of the disease:

• Injections into the skin : Medications are injected directly into the affected area. When anti-inflammatory drugs called corticosteroids are injected into the skin, inflammation is reduced and pain, redness, and itching can be quickly reduced.
• Topical treatments : Some medications are applied directly to the skin in the form of creams or ointments.
• Calamine lotion is often used to reduce itching.
• The doctor may also recommend topical corticosteroids, vitamin D-containing creams, or calcineurin inhibitors (drugs that suppress the immune system).

What if they are not enough?

Sometimes, the above-mentioned injections and ointments alone may not provide much relief. In that case, your doctor may recommend other treatments, such as:

• Cryotherapy : This uses liquid nitrogen to freeze large or very itchy warts. This treatment is often combined with corticosteroid injections.
• Immunosuppressants : These medications work by stopping your immune system from overreacting. This treatment may be given if you have Prurigo Nodularis due to an autoimmune disorder, such as lupus or psoriasis.
• Phototherapy : This uses ultraviolet light to reduce itching and help skin lesions heal. It works by calming immune cells that produce chemicals called histamines. Several treatments are usually needed.

Will this disease be completely cured?

Sometimes, there are cases where `(Prurigo Nodularis)` gets better on its own. However, as we have already mentioned, this is a chronic skin condition . This means that it can last for several months or even longer. Sometimes, the skin bumps may get better for a while and then reappear.

If you can identify the triggers that cause these bumps, it will go some way to preventing this condition from recurring in the future.

Serious complications from this disease are rare. However, infected lesions can develop. Scars or skin discoloration may also occur where the lesions have healed.

How can we protect ourselves from this happening as much as possible?

Although there is no way to completely prevent the development of `(Prurigo Nodularis),` there are several things we can do to reduce itching, further skin damage, and the appearance of new bumps:

• Avoid sunlight or use a sunscreen with at least SPF 30 .
• Keep your nails short , as there is less chance of damaging the skin if you bite them.
• Stay away from hot environments and avoid sweaty activities as much as possible.
• Use gentle cleansers and moisturizers that are suitable for your skin.
• If possible, wear long-sleeved clothing and gloves , especially if you are an unintentional scratcher.
• If the skin bumps are bleeding, be sure to apply antibiotic ointment and cover them with clean bandages.

When should I see a doctor?

If you notice any of these signs of infection, see a doctor immediately :

• If pus or other fluid is draining from a wound.
• If you have a fever .
• If there is pain, tenderness, or swelling around the wound.
• If the skin around the wound is red or warm .
• If you see red lines around the wound.

What are the important questions to ask the doctor?

If you have `(Prurigo Nodularis)`, don't forget to ask these questions when you visit your doctor:

• Are there any foods I should avoid when I have `(Prurigo Nodularis)`?
• Are there any home remedies for this?
• How to reduce the risk of scarring ?
• How to reduce itching , especially at night?
• Is this `(Prurigo Nodularis)` a result of another underlying medical condition ?

Finally, this is what I have to say to you (Take-Home Message)

`(Prurigo Nodularis)` can sometimes be a difficult and annoying condition to treat. It can last for months, sometimes even longer, and it can get better and then come back. When one treatment doesn't work, you have to try another, and this can get frustrating. Therefore, it is very important to choose a dermatologist who listens to you .

In the meantime, try to keep your skin in the best condition possible. It's hard to stop scratching, but scratching the nodules of `(Prurigo Nodularis)` will only make things worse, lead to infection, and scarring . It will also make the itching worse.

Keep your skin as cool and dry as possible. If you feel like scratching, try applying something like calamine lotion instead. Remember, you are not alone, and with proper medical advice and treatment, this condition can be controlled.
