Welcome to healthcare magic.
From your history, I could think of the following possibilities- cervical rib
, cervical disc spondylosis
compression. If the symptoms are acute or of a short duration, I would even want to rule out a cardiac problem urgently. You will need an ECG, X ray/ MRI of the cervical spine
to confirm the diagnosis.
It does not seem related to buerger' s disease.
Hope this helps you.
