I am experiencing tingling and pin and needle feeling in my hands and arms. Thought I noticed it in my legs the other day? I am female, 47, overwieght (205pnds) ,5feet 8 inches. I drive a lot for my job, I do have horrible posture. I have liposis so there is a lump in the middle of my shoulderblades. I am eating healthy and trying to exercise more. Shaking and flexing my hand seems to help this numb feeling subside. I do not take any medication. My first thought was I was having a heart attack or stroke, but I am hoping it is carpal tunnel or a pinched nerve.
