Im 58 yrs old, i been having stomach pain since february 2013. I had all kind of test. Endoscopy, colonoscopy, ct scan, ulra sound, and biopsy. The specialist cannot find anything unusual, i have acumulatio of fat on my liver, but my specialist said there is nothing to worry about. I been taking all kind of medication but nothing help the pain.Right now im taking elavil for 3 months. But im still in pain. What could be the reason?
