Muscle soreness on lower left side of right scapula
I've been playing tennis for 3 years now almost daily (borderline obsessive) and for the past 2 years I've been having this really annoying pain. Refer to the title for description. I only feel it when I am waking up and trying to be a bum in bed. It's a dull wave-like pain/discomfort that doesn't recede until I get up and start moving. When I stopped playing tennis for a month it completely went away. Maybe It's because I have bad form on my serve or over exert myself? Any replies are appreciated, Thanks.
