Mark, I've never had anyone closely examine my upper spine. In 2017 I had an MRI of my spine to look for a CSF leak. The MRI was clean. Beyond that I've never had any close examination of my neck.

My understanding (perhaps faulty) is Thoracic Outlet Syndrome usually involves symptoms in the shoulder and hands. That doesn't seem to fit my case. I don't have any pain below the neck. On the other hand my father has a cervical rib, which I understand is genetic and is associated with TOS. So I will ask my doctor about that.

It is good to hear that you were able to overcome your neck issues with therapy, Mark. I am always in favor of therapy and exercise over drugs. I will have to try to find such a therapist as you suggest.

I see a neurologist this week. I will also see an ENT on the off chance that something is out whack in my throat, which is where the pain emanates from.
