HI I have gone through your mail and as you said that you have chronic pain
on right side of your throat behind right tonsil it spreads to jugular notch,above it reaches up to right cheek it radiate to involve right upper arm.All these complaints direct us to think for-(1) Cervical spondylosis
,(2) Cervical Rib,But you sometime feel difficulty in swallowing that suggest some local lesion in throat.Thus you are advice to go for these investigations (1) X-Ray cervical spine
AP & Lat view.(2) M.R.I. Neck, (3) Upper G.I.Endoscopy.(4) C.T.Scan Paranasal sinuses
. After this please you consult your doctor for physical examination than after co-relation with inferences of investigations one may reach to final diagnosis which will help in treatment.Thanks.
