the information you are giving seems less to be from the tendonitis
. it may be from certain other conditions. there may some infammatory changes involving your muscles and both sides of arms and shoulders. to rule out these conditions you have to perform certain lab test namly ESR(erythrocyte sedimentation Rate
) and CRP (C-reactive protein
). if you find any abnormality in these tests then you might be suffering from inflammatory disease like tendonitis or myalgias.
but if you get these results normal then what i am expecting is that you are suffering from depressive disorder for which you have to overview your symptoms like pain in back neck, shoulders and radiating to both arms due to neurological distribution. insomnia
(sleepliness), loss of appetite, headache, irritability, aggressiveness, palpitations. so if your having these symptoms then you must consult your physician however what i would suggest you is to go for physiotherapy
along with the use of acetaminophen
get well soon
