yes, test were negative.

ok understood.

I didn't pick up from your info that that this 6 month period was a period of mania.
So, you suffer perhaps, from bi-polar disease? I don't know if Cymbalta works with that. I do know that there is a drug that is often used for both unipolar (anger/rage related to depression) and bi-polar called Lamictal. I'm not suggesting it. I saying, as about it. Perhaps your mania is severe enough for Lithium. It's the only thing that works for some people. It's also worth asking about. If you take care of some of the heightened feelings the pain you are experiencing may not seem to bad or urgent. Go see your shrink, ASAP (psychiatrist, medical doctor) they know a great deal about how all the body functions and neurological aches and pains work in conjunction with the psychological stuff.
Just a suggestion.
