Dear doc,          My husband is left handed and aged 30yrs is suffering from left arm n shoulder pain since 4 weeks. Some times he tells there is a slight pulling pain near side of the neck. we have visited orthopaedic and as advised tablets n hot compression with some physiotherapy. It has reduced now almost 60% as he was in rest for a week. Still have slight pain and discomfort during day and in night times it is more. Hence not  getting continuous sleep. some times it agrivates. Doc has told there is a muscle compression near neck.. trapezious muscle. Please advise its been 4 weeks.. He is not feeling  comfortable still. He is a software professional.
