I'm a 20 year old female and I have chronic upper back pain that is unbearable at this point. I was involved in a car accident three years ago where I was t boned. I've been to all kinds of doctors and have found out nothing. The pain is stabbing between my shoulder blades and radiates to my chest and my arms. Anyone have any ideas? I've had blood tests done as well and the only thing they could find were positive Ana levels but even with further testing nothing was discovered or diagnosed. Please help!!!!
