Does anyone wake up w biceps soreness that are side sleepers? When I wake up on rt side mostly I have bicep sore, espec if I take a valium bf bed as this makes me in a coma so I'm on one side too long. Was hoping Pec m surgery would of helped this, but doesn't look like it has. I haven't heard anyone on here complain about biceps pain. I dont think my surgeon knows why I have this sx. Ive had this sx since 2009, and 3 surgeries I thought would of helped! So strange wish someone had answers to why st least!
