in the past 2 weeks ive discovered small bumps on the head of my penis. they grew in size but was never itchy or painful at all. in total there are 3 the head one thats about 1mm one thats about 3mm and the other 4mm. i later discovered a smaller bump that was on the right side of my shaft, about half ways down, but this one itched, and itched a lot. Also the underneath part of my penis itches a lot but theres no visible abnormalities. but just recently there was a small bump right under the head of my penis on the shaft, and that was itching like crazy and i think in my sleep i was scratching so in the morning it was a little swollen, so i just iced it for a few minutes and it went back down. ive seen a doctor and he said he hasnt seen anything like it before but did a blood test for std, but that results wont come in til next week. other than the itching and the weird look to my penis, this hasnt caused much problems. but im just wondering what the heck is going on. i thought at first it was hpv, but my doctor said it doesnt look like it. i think its just weird that the bumps on the head dont itch at all, but the ones on my shaft do? if you could help this would be great. thank you
