sholder muscle pain
I have reoccuring sholder muscle pain in my right arm. I believe the original injury occured in September lifting a heavy object.
The pain seems to be agrivated when I use a computer mouse extensively or if I sleep with my arm extened over my head. The pain is alway present and fluctuates only based on activity. The muscle is visibly different between the 2 arms and slightly tender to the touch.
My questions are:
1. Is this an injury I need to see a Dr for?
2. Home treatment options I should consider?
3. Possible ideas as to what I should do? Thank you for your time and assitance.
