I frst experienced Upper back pain from may 08 - mid septemberr 08. I am not 100 % why I had the pain. I saw every doctor imagineable (orthopedist, rheumatologist, acupuncturist, physiatrist, myofascial trigger point therapist, massage therapists) Not much helped but it went away towards the end of september) My only symptoms were upper back pain. The muscles were very tight and knotted.I was not fatigued and sleeping was not an issue.
