Hello and hope you are doing well.
Fibromyalgia can produce these symptoms (tenderness). Fibroids cause back pain. Sometimes repetitive injuries or strain can also produce these symptoms. Inflammation of the muscles, joints and surrounding soft tissues like bursa can also cause pain.They are diagnosed by a physical examination. Sometimes blood tests, x rays, bone scan, CT and nerve conduction studies can help clinch the diagnosis. Treatment usually depends on the cause and painkillers are given if the pain is severe. Please discuss this with your doctor am sure he will provide further assistance.
Hope this helped and do keep us posted.
I am sorry I hope it has eased now ...have you been prescribed any painkillers ..what treatment were they starting for the tumors ?
