So I had a whitehead--a regular pimple that would be on your face on the shaft of my penis and I gave it a couple of days until I decided to pop it. When I did I squeezed quite hard which I will admit to make sure I got out everything. I've had these before so I never thought twice about it and I am sure that it's not a std because it's been about a year since I've even had sexual encounter and my tests came out negative. Anyways, I'm guessing the day after or twos day after I have been getting a soreness in my groin area as well as my shaft like its kinda tender and I don't know if I squeezed a vein when I popped the pimple but every time I touch my penis well the shaft it's really sore and I've felt another lump on top on the shaft which may or may not be a pimple given that it could be just a vein. I do take blood pressure medicine and I take lisonpril 20 mg but I usually take 3 pills a day. Not sure if that has anything to do with it but I'm just concerned of what it could be.
