My right arm feels cold

Nearly 3weeks ago I had a fall and badly sprained my ankle, not able to walk yet as bruising &, swelling not gone down. Three days ago I awoke with a tingly feeling in my hands and legs, no pain and though my legs feel ok I cannot seem to get my hand warm. Could this be associated with my fall and not being mobile yet although I move around on my hand and knees

Angela, I know this is many weeks but have you had any exam by a Dr? Maybe XRay or nerve tests.
I assume when you fell, you used your arms to steady yourself. You may have trapped a nerve in your wrist. If you are still having problems, you urgently need advice.
