The tip of my left ring finger is completely numb and the tips of the baby and middle finger on the same hand are tingly - like pins and needles. My entire left hand doesn't feel quite right to be honest.
For about 10 years now I've had what I call 'arm pain'. My left arm, shoulder and side of my body get really achy - like growing pains when you're a child for lack of a better description. This feeling comes and goes and it's hard to pinpoint what sets it off or what makes it stop. When it's at its worst, my left hand goes entirely cold and it feels heavy - like it has no strength.
This permanent numbness in fingers and constant tingling is a new thing though. Any ideas what the hell is causing this?
