Michelle,
It took me 2 years to find out the pain in my lower left abdomen was nerve damage due to previous surgeries so don't give up I had every test there is done and then finally some suggested I have a nerve study done and they found it and I was no longer crazy or left in pain I had to go to doctor after doctor and if I felt they didn't believe me or were just not listening I would switch again I won't kid you it is very hard to do but if I hadn't persisted I would not be doing as well as I am now.
I wish you the best and don't give up there are good doctors out there just getting hard to find these days!
