For the past few days I have had a dull ache in my testicles...periodically. Usually in the mornings and in the evenings. I have heard this can be caused by wearing clothing that is too restrictive and I think that may be the case since my trousers are quite tight. Should I get this looked at or is it one of those things? I am 99.9% sure its not an STD but am wondering what it could be. I also had very sharp pains in my lower abdomen this morning which caused me to double over...I don't think the two are related though. I think the lower abdomen pains are to do with IBS.
