The past couple weeks I ve been having very bad jaw pain, shoulder/shoulder blade pain, and leg pain above my knee I ve tried sleeping different ways and such and taken meds, normally I wouldn t think nothing of it, however its all on my left side and nothing really helps it, I didn t know if it was just a coincidence or if that was symptoms of something with it all being on my left side. I m only 29 years old, if that helps any.
