Does prurigo nodularis come back after UV treatment at 22?

Question

Hello doctor,

I was diagnosed with prurigo nodularis at a young age and underwent ultraviolet (UV) therapy last year, which honestly helped a lot at first. The itching finally calmed down, and the nodules flattened, but now a few spots are slowly coming back again.

Does prurigo nodularis return after UV treatment at 22?
Is relapse common once phototherapy stops?
Does this mean repeated UV treatment may be needed long-term?

It is frightening to think this may be never-ending, especially at this age. It is mentally exhausting to worry that skin problems may always control life. Sometimes, social situations are avoided because of fear that people may stare or ask questions.

Kindly advise.

Hello,

Welcome to icliniq.com.

I have read your query and understand your concern.

I am sorry you are dealing with this at such a young age because prurigo nodularis can be physically and emotionally exhausting, especially when the itching and visible skin changes begin affecting confidence and social life.

Unfortunately, relapse after ultraviolet (UV) phototherapy is not uncommon. Many people improve significantly during treatment because phototherapy helps calm inflammation and reduce the itch-scratch cycle, but prurigo nodularis is often a chronic condition, and symptoms can gradually return once treatment stops, particularly if scratching, stress, dry skin, allergies, eczema, or other triggers continue in the background.

A relapse does not mean treatment failed or that the condition is hopeless. It simply means the disease still has underlying activity that may need ongoing management over time.

At 22, there is still a very realistic chance of achieving long periods of good control, and many patients do not need continuous UV therapy forever. Some people need occasional repeat courses during flares, while others transition to maintenance skin care, topical anti-inflammatory medications, antihistamines, or newer targeted therapies if the disease becomes more persistent.

Newer treatments, including biologic medications, are also often used in difficult cases, especially when itching severely affects sleep or mental health. The emotional burden described is very real because chronic visible skin disease can affect self-esteem, relationships, and daily functioning just as much as the physical symptoms themselves.

If the condition is causing social withdrawal or constant emotional distress, it is important to inform a dermatologist because quality of life is a major part of treatment decisions, not just the appearance of the skin.

I hope this is clear, and if you have any questions at any time, please feel free to ask.

Thank you.
