I sleep on my left side. Now, not only am I getting pain in the left arm, I am now starting to get a tingling
sensation in my left arm down to my fingertips, which happens mostly during the day. There are some changes, I have been excercising and walking within the last month. We have just recently added weights, but the pain and tingling sensation started before the weights. My diet has changed to grains, vegetables, fruits, lots of water and very litte meat.
