It happen during aggressive sex but me and my girlfriend have a lot of it. I happen to miss my mark so to say and my penis did not penetrate when I thrusted aggressively. So my penis got tucked down and the base of my shaft hit. I did not feel any pain at the moment and didn't even notice anything wrong and continued with our sexual activity. At this particular time were pressed for time so we had to leave quickly, I did not release (not because I felt like I could not but because we had to go). As I was pulling up my pants I immediately noticed a very large half the size of a golf ball bump on the base of my shaft. It didn't not hurt but you could imagine my panic at the time. The bump was very large, did not have any discoloration, and did not have any pain at the time. I was out of town at the time of the nearest ER was about an hour drive away. My house was about 3 hours away. I started driving home in about an hour into the drive the ball went down tremendously but did not go away. Now it was about the size of marble, a bit smaller, and still no pain yet. I made it home and decided to wait it out. The next morning I went to ER. They told me it was a soft tissue contusion and to ice it and take Tylenol for the pain and wait about a week for any sexual activity. About 4 later I received oral stimulation and upon release it was very unenjoyable. My penis got real tight and felt like he was forcing itself to release. That marble like ball on top of the shaft of my penis just looks like a very sore vein. Now this sore, slightly inflated vein cause me pain when ever I get erect and point my shaft down. (No erectile dysfunction). I when to a urging care days later and they told me the same thing and just gave me a prescription for ibuprofen. It's been about a week now and I haven't seen any improvement. I just want to know how long this thing usually takes to heal or anybody has been through the same thing? Any input would be appreciated, thank you!
