I am a 60 yr. old female diagnosed with Chron s Disease, Diabetes, Thyroid Disease, Barrett s, some kind of inflammatory arthritis. I am continually exhausted, and hurt all over, muscles, bones, joints... What could be the source of my extreme fatigue and body pain. I recently started a walking regiment and was doing several miles a day, then I was knocked off of the routine when all symptoms returned full force. I work full time and have little left for anything else.
