question: Hello doctor, I am 29 years old. Since the last 10 days, I am having a serious red swollen tip of the penis with burning and stinging after urinating. Initially, I thought it might be because of UTI. So, my doctor had written for urine routine test and urine culture test which came negative. But the red swollen tip is still there and its burning. Ever since I got this, I am observing I am not having erection or urge of any kind. My doctor then wrote for CBC, PSA, sugar check (in case of diabetes), serum creatinine, ultrasonography of abdomen and pelvis. These reports came to be negative. He currently had given me Augmentin 625 Duo if there is any bacterial infection. I am worried as the tip of my penis is red, swollen, looking like lips and burning for more than 10 days now with no libido or morning erection at all. Please suggest me what to do.
