I am not a prfessional, but have been having a lot of various types of back pain. To me, your description matches what I had that my doctor described as neuropathic pain.
After trial and error, the medication that has worked wonders for me is a very new one called "lyrica". You will see a posting I did recently on this topic. The subject line mentions neuropathy and lyrica.
Ask your doctor about it, and whether he/she thinks it might help.
Personally I had a tingling/burning sensation of much of my thoracic region. As I said, it sounds similar to what you describe in your arm.

Thank you....I am actually on my way to the doctor and I will mention this medication to him.

What you described is typical of a shoulder problem getting worse with secondary nerve entrapment in the elbow and at the brachial plexus. This may even involve the hip flexors, but unfortunately, most people look at your symptoms, not at how your body functions. This is an important distinction since I have resolved many obvious problems by looking at a persons body structure first, and seeing what they are predisposed to structurally, and then looking at the ensuing symptoms.

Thank you for the information. When I went to the doctor he told me that since at that time there was no weakness in my hand or arm that I should just take an anti-inflammatory and that it should heel itself in a few weeks. It isn't getting better and now I am experiencing weakness in my hand and my pinkie and ring finger as well as that part of my hand either gets really cold or really hot. I will check out your website. Thank you again.
