Can severe work stress cause Fibromyalgia or is it silenty underlying and severe work stress bring it on? I began having pain in my elbows and numbness in my 4th and 5th fingers due to rep. motion and position at my work space, and added newly physical requirements over the last year, and along with severe mental work stress, I went to seek medical attn. Shortly after a visit to the ER which severe mental work stress issues were discussed, I began having total body pain, with continuios sharp shooting, deep agonizing tendon, ligament, muscle, bone and joint pain. I am now having extreme fatigue during small physical tasks and irritable bowel disturbances up to 4 times a day. Last week my Dr. said I may have Fibromyalgia and would refer me to a rhumatologist. I am 52 and female and now unable to work. I feel like I am on a rollercoaster at a fast speed with no up in sight.
