@urkoslo They are separate problems, but both can be caused by trauma from an accident or repetitive strain, so I think TOS may be more common in spine injury patients. TOS often involves the scalene muscles that can be injured or form scar tissue. Scalene muscles also connect to the spine, and the brachial plexus bundle of nerves and circulatory vessels pass between the heads of the scalene muscles and continues between the rib cage and collar bones. There is another TOS compression point under the Pec minor muscles. I was in therapy for TOS, when the spine issues started to become evident. Those are classic symptoms of raising the arms and increasing symptoms and tingling in the pinky finger. I think having both issues just confuses the spine diagnosis because of having overlapping symptoms. That's why I came to Mayo because they could evaluate both.

Here is some information.
