Severe back pain between spine and right shoulder blade, that after time being on my feet, causes lightning bolts down and around my back. Okay, I have had the MRI done, 2 spine doctors say there is nothing there to be causing that kind of pain. I have had a steroidal injection, taken a steriodal drug, a non-steriodal drug, and a muscle relaxer, and guess what nothing has helped. The neurologist put me on Lyrica to help the lightning bolts, but ended up hurting my legs worse. Or could my legs hurting be a new symptom of what ever is wrong with me! One spine doctor told me that maybe there is something going on inside my chest cavity that could be causing the back pain! I guess what I am wandering, if maybe there would be some kind of chemical imbalance in my body for my muscles to be feeling the way they have been. But there again, with the 2 gallons of blood I have given in the last year, surely they would have found something! Like I have told people, I could probably handle the pain, it's the not knowing what's causing it that is killing me!
