With regard to ur suggestion I did consulted a dermatologist and he said its because loss of pigmentation and prescribed tacrotor 3.3 wt% ointment. I am applying for last 1.5 months but didnt notice any significant change.
Hello,
Without external examination it is very difficult to confirm a diagnosis,but the various possibilities for your symptoms are folliculitis(might only be felt as small lumps in the skin commonly with a hair arising from centre) , pearly penile papules(multiple, small (about 1-3mm) papules running around the circumference of the crown of the glans penis) , Fordyce spots (small (1-5mm) bright red or purple papules that can appear on the penis and usually effect younger men), sweat dermatitis or contact dermatitis(appear as red small lumps with itching or burning) or balanitis(due to an underlying infection (bacterial and fungal as well as other organisms).
I sincerely advise you to consult a dermatologist and get yourself evaluated for these possibilities.Till then, you should keep the area clean, wear lose comfortable clothes to avoid sweating, use a powder to keep the area dry and use calamine lotion at the site. Oral antihistamine medications would help if the lesions are itchy.
I hope it helps. Take care and pls do keep me posted on how you are doing or in case you have any additional doubts. Kind regards.
