My right leg on the calf n the back feels ice cold. i have it wraped in a blanket. ?

This sounds: like "false" temperature "signals" to your leg from nerve fibers irritated in your back (specifically L4-5) Although its unusual for JUST the Temperature fibers to be iritated it is the only condition which occurs to me! Do you have back pain? Any injuries??? Hope this helps! Dr Z

See doctor: If this is suddwn.ir could be a vaacular problem see a doctor to evaluate for.arterial or venous problems
