Hi..
Thanks for contacting HCM for health query..
You have pain which is from the middle of the arm to the elbow that is making you decapitated..
You are right ,I too agree that the pain is not from shoulder..
Pain is from the mid arm to elbow,i feel it should be muscular origin because movements precipitate pain..
Madam since you have not given history of sudden excessive exertion,it could be Muscle catch..
If you remember a history of sudden unaccustomed severe muscle stretch it could be a muscle tear also.
If I have a patient like this in my outpatient department I would give him/her an
analgesic,
cold sponging and rest for a week,observe and then if pain continues I will proceed with
MRI arm.
Madam meet a doctor in person as it is annoying you..
Hope our input helps you..
Take care.
