It could be a bladder infection or kidney infection or maybe an ovarian cyst?
I have a similar problem. Except I do discharge blood. I've had Ct scans, internal scans, blood work, been told I might have Crohn's, then after another procedure, told I don't. It get's so bad, sometimes I cramp up, and have to uncramp myself. It seems my internal organs move inside. I have had this intense pain on my left side only the last few days. I usually have it on my right side. The pains began years ago, and I've spent a lot of money, not knowing what I have. It *****.
could be a water infection can give alot of pain and if left too long can go to kidneys with fishy dischrge
