Psoriasis is a long-term skin condition that cannot be completely cured, but it can be well controlled with proper treatment. Doctors may suggest non-steroid creams, medicated moisturisers, vitamin-D-based ointments, or other newer treatments to reduce scaling, dryness, and itching. Keeping the skin well moisturised, avoiding stress, and following a healthy diet can also help manage symptoms. Some supplements, like vitamin D or omega-3 fatty acids, may support skin health, but they should be taken only after medical advice. Since you also have itching around the testicle area, it is best to consult a dermatologist to rule out any fungal infection and get the right treatment.

Psoriasis commonly recurs because it is a chronic immune-related skin condition that can flare up due to stress, infections, weather changes, or stopping treatment early. Restart prescribed topical treatments and keep the skin well moisturized. If the flare is severe or spreading, consult a dermatologist for proper adjustment of therapy.
