Well I'm not sure f this is right place to post this but I will anyways
Yesterday morning I had to pee and right after I did I got a sharp pain for bout 5 seconds when walking but went away. Later that day I would get occasional pain in penis shaft area but wouldn't last more then 2 seconds. Also I was holding in my pee for about 4-5 hours the last couple of days due to not being a bathroom were I work. I would get a constipated feeling also like I can feel the urge to pass gass but it would build up and hurt really bad just under my testicals when trying to push it out..same with peeing although I don't get a burning sensation when peeing it only hurts after or before I have to pee. This also has happens before but I never got it checked out but what happens for both times was I went pee and went really fast and then ran back to what I was doing but while I was running all of a sudden I got this sharp pain when I walked or moved and it lasted bout 5 min and went away and didn't come back till maybe about idk months though but same thing happend right after going pee and couldn't move and was soar in the testicals region for 2 days but I never got it checked out cause it usually went away. But now I got a doc appointment today and we will see cause it hurts really bad and my stomach keeps growling and feels like I'm full of gas and it's just a pain! Please help what do u guys think it is btw a 17yold male
