<s>[INST] I have a throbbing pain on my right hand side. It began off and on a couple of months back. Now it is effecting my sleep, and daily activities. It has begun to be constant in the last few days. It is directly on my side around the middle; above my hip area. [/INST] Thank you for question. 1) Thoracic Outlet syndrome: This is a condition where the subclavian artery may be blocked leading to throbbing pain. The reason could be a) Cervical rib: Get an xray of the neckb)Scalene muscle spasm: Try a muscle relaxant Flexon mr 500mg and see if it relieves pain.c) Others: Discuss with your orthopedic surgeon2)Nerve impingement:a) Cervical spondylosis: Get an xray cervical spineb) Osteoarthritis of medial epicondyle: elbow xray and examinationc)Ulnar nerve traction: Get a nerve conduction test. d) Saturday night palsy: Did u fall asleep on a chair with your arm hanging on the side?Hopefully you dont have a previous fracture around your elbow or it could be a complication of that.Get well soon </s>
