I have had the same problem for the past two months. I had an encounter of a sexual nature, but no sex, just friction - no penitration. Also, I had many other environmental factors that could be at play - bad diet, lots of alcohol, hot weather, and some other factors.
After many hours and hours of research, I figured that I have an issue with Yeast/ candida.
I am trying the candida diet right now, and I will see if that helps. Ill keep you all posted
HSV is very obvious and I don't think is your problem. I had a recurrent balanitis for 1.5 years and everything started after a yeast infection. I took fluconazole and used ointments and nothing helped me, the red spots were still there. Finally I went to another Urologyst and he suggested me to circumsice my penis and after thinking so much about it I went for it. The redness cleared right after the surgery, More than a year since the operation and my penis still looks very healthy without any rash. Your problem may be different than mine, so I suggest you to consult an Urologyst.
I'm uncircumcised and have the same problem. mine started when I had sex with my girl friend for the first time. I got a yeast infection that time from a LOT of sex. We did it like 9 times per day at the beginning for 3 days in a row. After that my glans was in pretty bad shape and in a few days I developed and yeast infection. This infection cleared up with a topical cream accompanied by a 10 day course of Fluconazole 100mg (one per day) but the red bumps under the skin remain. As some other have commented, the bumps are most apparent when erect and are made worse with friction of any kind. I suspect this may be viral and given that it's been there for one year now I think it will not clear by itself. If I had to guess this is probably related to the HSV... unfortunately.
My previous guess at this being Lichen Planus, or Nitidus i think is wrong.. Protopic is also most likely to be harmful and cancer causing... anyways, because of this being closely affiliated to friction, I got reading on "Keratinization" which is your glans drying out due to, friction, from not having a foreskin because of circumcision. You can restore your glans as well as your foreskin and I encourage those desperate for a cure to give it a go, cause it's not looking like there is a cure.
I also Have dis..i have rashes on my penis but can be seen only when its enlarged..and i got rashes inside my mouth also.i tested for std n results were all ok.n my dermatologists told me its yeast infection n gave me clotrimazole but its still not working..wat could it be.? How will i get cure.
I too have the same symptoms although I think mine could have been cause by sexual transmission. I slept with this girl for months and one time she wanted Anal. So I did but I had a small concern cause I thought I saw a couple of white curds in crack area. I thought it would probably be a yeast infection and since I was so in the mood, decided I could clear it up if anything were to show up. (I have seen pictures of yeast infections and they dont look the same as to what I saw and cant find anything that looks similiar. I also asked her for help and she has no idea) That was in late october and and I stopped dating her in December. In late Feb, I noticed just a small red irritation on the side of my shaft but not on the colored part of my skin. I haven't had any discharge, painful urination or anything other than red irritation that know went around my penis but not on the shaft. I went to the doctor and he couldnt see anything. Its been a year and a half and the only thing I know that works and makes it feel better is using hydrocortison and putting on some gold bond afterwards to keep it dry. If I don't I feel discomfort, tenderness and sinsitivity around the tip of my penis. I too feel that its red in my urethra and may see a sore but cant tell. I know started to see small little bumps trying creep down the shaft as if it were trying to infect the pores of my penis. Or it may be due to the powder I use that do that but I dont think so. I was given cicloporox by my doctor, along with Diflucan. At one point, I thought I had a UTI and went to the doctor but came back with negative results. I had some abdominal pain but went away with ciprofloxacin. I still have this red irritation and if I dont keep it dry, it stays tender. I dont have any other symptoms other than I have always had small ecsema on hands if i dont keep them lotioned.
Any help would be appreciated.
