Red foreskin

How you doing guys, hope you had a nice Christmas.

I’m currently taking a break because I had (a minor injury?) .
A couple of days ago I was doing a decent workout with a good warm up under the shower. I started with some stretching with a self made stretcher (shoe lace and a bottle attached to it) and continued with some pumping afterwards. I pumped really strong ( don’t have a gauge though so I can’t tell) but it didn’t hurt in any way, and just a few red dots (2-4). Then I rounded it up with 15 mins of jelqing. Everything was fine and my dick got really thick and veins were showing, so I had the conclusion everything went fine.

A couple of hours later I went to the pub with some mates, and suddenly had a weird urge to pee. It didn’t hurt, itch or burn, it was just a really weird feeling. When I went to the bathroom I also had no problems to take a leak, everything was fine except this weird feeling. When I rolled back my foreskin, it was red and swollen and felt a little numb where the redness appeared. That weird urge to pee went away after one day, but the swelling and the redness are still there. Any advice guys? Oh and by the way, 3 days have passed since I was at the pub.

This is my first thread, so don’t hesitate telling me if I did something wrong ;)
