I went downstairs yesterday to put something away, and i was standing there cleaning one dish, and suddenly my left testicle starts throbbing with that dull ache, that goes into your stomach. I'm sure anyone who has been kicked in the crotch will know the pain well. The problem is, i didn't do anything. I limped myself upstairs, and laid down. If i didn't more for long periods of time, the pain dulled, but the second i moved again, it would come right back. I tried taking some vicodin (pain realiver), and soma (muscle relaxer) that i had for my back, to see if it would relieve the pain, but it didn't do anything. So then i took 4 motrin, and a tramadol (another pain reliever). This helped. It allowed me to get some sleep, but it is still sore. The pain is a lot better, but i still have to be careful, because it is very sensitive. I went feeling around last night, and i didn't feel anything extra, but my left testicle was very sore, and sensitive to the touch. The other one seems fine, no problems on the right side. Any ideas why this happened? I'm 21 years old, and this has happened once or twice before, but it either goes away in a few hours, or a few days. Any ideas? And please, no jokes, this is a serious problem.
