For nearly a month now I have been having problems with my shoulder/back. It feels like someone has there hand under my shoulder blade and I get a tingling/tightness sensation with pains in my arm and shoulder blade.
I have also had pain in my left leg for a couple of years. And it really hurts to press on my spine in the bottom. Not sure if this is related.
I feel as though this could be something serious such as spinal cancer that has spread. Does anyone know what this could be?
