I have had a pinched nerve in my back for about 4 years now with no flare ups. 6 weeks ago, I heavily sprained/twisted my ankie and landed on it. Since going into physical therapy I have discovered that the back of my calf is numb-when I do leg stretches of any angle, I NEVER feel it in the back of that calf. Now, on the same side of my body, my right hand suddenly started tingling like it has fallen asleep. Am I looking at a stroke maybe, or could it be from the fall or the pinched nerve?
