I recently noticed the corners of my lips were getting dry and cracked. I used chapstick for a couple of days to no avail. After 3 days the cracling became so bad. A day day later before going to bed my penis began itching alot. A day later the shaft of my penis swelled to twice its normal diameter. The itching is unbearable and the skin around my penis is swollen really bad. Aside from the cracked lips "corners" and the itching and swelling at my penis, I have no other symptoms. My penis definitely has a rash, but no blisters, ulcers etc. I was tested for herpes 2 yrs ago which came back negative. I just am worried the cracked corners of my lips and penis must be related. I have not had sex in 5 months. These symptoms just appeared recently. I went to a urologist who examined my penis and prescribed cephalexin pills and a cream containing clotrimazole and betamethasone. He thinks it may be a yeast infection or fungus. also the corners of my lips only are cracked and ulcerated, not the inside of my mouth whatsover, also I no burning or pain urinating or discharge. Any ideas what this could be?
