hi welcome to HCM
-had gone through your query and understand your concerns,i would come up with the possibility of CERVICO BRACHIO
NEURALGIA caused by CERVICAL SPONDYLOSIS
-it is due to degenerative changes in the cervival spine
-strees
-general poor health
-long stooping posture
-deficient calcium in the food are some predisposing factors
MRI scanning for
cervical spine may confirm the diagnosis
wishing you good health
