I am experiencing considerable pain where my left arm connects to the front of my torsoe and minor pain in the same area on the right. Can’t say what caused either, just appeared several weeks ago. Range of motion is very limited on the left, so much so that reaching backwards causes a reinjury of that area bordering on excruciating pain. Should I go to the chiro, doctor, or other? Or just be cautious of motion with the hopes of it healing?
