Could the persistent redness and swelling at the opening of my penis be a bacterial or fungal infection, what is causing it, and is this normal, considering my STD tests are negative and the condition has not improved after using medications like Zifi CV, cefixime 200, SN15 plus, Flucazole, Lyser D, and ointments like Tbact, Onabet, and Fucibet?
Since your STD tests are negative and multiple antibacterial (like Zifi CV, cefixime, and Tbact) and antifungal (like Flucazole and Onabet) medications haven't helped, the cause might not be an active infection. Instead, it could be contact dermatitis, irritation from using many topical treatments, or a non-infectious inflammatory condition. Please rest assured that this is manageable. I recommend washing gently with only warm water, stopping any harsh soaps or extra creams, and consulting a dermatologist or urologist for a tailored evaluation to help your skin heal safely.
