Hi friends, I am experiencing moderate pain in the back ( its not in the lumbar region but mid-thoracic and I guess its serratus posterior inferior because I can't twist towards left as pain is on the right side) and it occurred the next day I exercised shoulders. The cause I could figure out is that I was trying to lift heavy dumbbells in seated shoulder press and may be it was too much of extension. The pain almost subsided in these four days, I took a medicine as well for pain. I did shoulders today and there's some pain again in the same region. I am concerned now and don't want to skip workouts at all by complicating anything, please suggest what must be done to prevent further occurrence of pain.
