I have not been ruled out for those. I had an MRI of the brain which was normal. Would they have noticed something of this sort? Also, with respect to Thoracic Outlet Syndrome, I donāt seem to have any of the other symptoms this disorder presents.
I will check out the subclavian fistula in the brain.
No, MRI wonāt. Please see the articles that is on my Facebook page link to understand the new knowledge on Thoracic Outlet syndrome ( cervical outlet syndrome )
Please keep a diary to what you did before the symptoms started. That will give you a clue. For me , it was my sitting (slouched) , lying on left and my arm movementās. I also weaken my left radial pulse when I go through the symptoms.
