Dear friend, welcome to HCM,
you seem to have cervical spondylitis
and hence the reflex spasm
and pain in the neck and shoulder area.
you would need detailed evaluation for the same. till then can take combination of acetaminophen
, a muscle relaxant
like doxazosin and a NSAID, under supervision.wear soft neck collar for support.
take care and pl. keep me posted on the progress.
