I had failed surgery in January 2005. Eight months after the surgery my surgeon ordered an MRI with a radiologist who specializes in TOS and he said I had scar tissue building up on my brachial plexus. Both the radiologist and the vascular surgeon explained that the scar tissue was the reason for the continued pain. Several doctors have since told me that scar tissue on the brachial plexus equals chronic pain.

My surgeon did use a wrap in an attempt to prevent scarring but it didn't work in my case.
