I've been having some right calf pains, dull sometimes crampy, goes and comes. It causes my foot to become cold tingly or feel like its going to sleep. I have visit doctor and had an ultrasound done to see if blot clot was issue. Test came back negetive. If i elevate it, there is no pain and walking doesnt seem to be a problem, pain goes away. just mainly when i'm at rest does it cause discomfort. I'm 25 and concered,
