Hi I have woken up with pain startin where my bra strap fastens to the left but more up towards my shoulder blade it is going worse so when I move my head it really hurts and can feel it in my chest where my breast bone is more to the left hand side, sometimes with a bit of a shap stab in the bust, even when i move my arm left one or my leg depending where I move it really hurts, i can not move so lie in down but pain unbearable when i want to turn etc, could this be a trapped nerve or should I go to the doctors , it is really worrying me now I m 47.
