John, You are not alone . I hurt the same way you have said. I have had mris bone scans xrays blood test cat scan everything I have tried all ended up with nothing it is very hard to try and live life anymore because of this pain. I have been looking for an anwser for years all my doc gives me is pain meds I would really like to stop hurting its been 11 years and I dont know how much longer I can last. I am 31 and my pain started after my first child was born in my upper back seems like no one cares .
