Suggest Treatment For Pain In Abdomen, Muscle Weakness And Cramps

For the past five years I have had muscle weakness, cramps, spasms and generalized fatigue and sleepiness which is getting worse. As well as a constant pain in my abdomen that is constant. I have never slept well, and never wake up refreshed. In my first MRI I had 3 lesions, which then became decreased to 1, which during both were ruled insignificant. During my sleep study I had a 103 spontaneous arousal. I had several blood tests done all which came back okay except I was told in one of them I had slight inflammation. I was told I have IBS and Fibromyalgia. Is it possible that there is something else.
