Hi doctor, i have bumps/blisters/redness with heavy itching and irritation on my outer back side of penis (mostly on perineal raphe). Its been here since 2-3 years. I had hiv, herpes, vdrl, tsh tests in 2014 & all tests were normal (negative). Now i gone to doctor and he gave terbinafine & mometosone furoate cream base with itraconazole 100 mg 10 capsules. treatment cleared 50% problem but after somedays itching irritation bumps starts again. Please help me what can i do for this? I am very tensed. After every treatment it came back within few days.
