Suggest Treatment For Calf Pain With Numbness And Tingling In Feet

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,
