I have constant pain in my lower abdomen. Sometimes its on the right side and sometimes its on the left. I have done every single test including an M.R.I. and they have found nothing nor can tell me what it could be. I have had a testicular torsion in 2007 and have asked my urologist if this is the source and he said that its most unlikely because none of his other patients have had this problem. It feels really tight when it hurts and gets worse when I do anything Physical. Hernia, infection and anything physically wrong has been ruled out by testing, can anyone help? I've even gone on a full body cleanse and that didn't help.
