Hi, following an injury 10 years ago i have had terrible neck and arm pain, with shoulder dropping and feeling of arm weakness. following various diagnosis's the pain spread, now all over in bones nerves and muscles. Have osteoarthritis def in lower back, neck and shoulder. Fibromyalgia mentioned but now told don't think is but saw they wrote rheumatism as primary diagnosis. Am constantly exhausted but told result of chronic pain, not me. Has anyone else had this catch all diagnosis? I understand not commonly used term now but got it from an excellent hospital.
