Yes Rachael,
The inter costal clavicular nerve. That is the one that bothers me that I feel like I have a pager on vibrate on my boob.

It comes from under the armpit area across the chest. TOS mimics so many symdroms, also why so many see many doctors and treated for many things before getting a brachial plexus syndrome diagx; TOS.

Having a doctor that understands TOS, can diagx it is such a great help for answering questions. Many doctors though are too busy or lack a lot of information on TOS.

With a forum like this we have combined hundreds of years experiance, symptoms, and support.

Upper Back
Back to Top
Upper back pain can be caused by a variety of conditions. Some of these conditions can be directly related to neurological (nerve) irritation of the inter-coastal nerve running through the muscles traveling through the ribs. Other pain causing conditions are referred pain from internal organs such as the lungs, gall bladder, and stomach.
