How Can Penis Glans Pain Caused By Trauma Be Treated?

Hi, may I answer your health queries right now ? Please type your query here... I just has sex with my girlfriend and right before I came, she squeezed my penis so I wouldn't ejaculate and would last longer. I think she was a little late as I felt my penis pump a few times in her hand but it wasn't an obvious ejaculation. We continued to have sex until she came and I was losing my stiffness. Afterwards I went to the bathroom to clean myself off and take a piss. I experianced a tremendous pain in the tip of my penis and it took me minutes to slowly pee knowing how painful every squirt was. I don't have to pee anymore but bellow the tip of my penis hurts incredibally if you touch it. It's not a light pain at all.. Infact I can't help yelping if I move the wrong way or it hits my leg. It's been about 30 minutes and I'm afraid to move because the pain is so severe. What should I do?
