My left arm, and left chest have been both suffering for long time. I didn't have any shortness of breath. The other day, my friend took me to a Chinese masseur, an old man. He pressed my hand along my arm to my chest, Wow, that was so painful, he said the road to the lung is blocked, or whatever. It was so painful I yelled loud. I almost cried. Having some bruise along my arm now. But, Jesus, that's incredible, I feel so much relieved, no more dull pain.
