Hello. I ve had pain in the front of my left thigh, between my hip and inner thigh. The pain is dull and runs down my leg to the back of my knee and to my ankle. The pain throbs sometimes but not continually. It also looks like I may have a varicose vein in that area too, really blue vein. This really hurts when I sit for 30 minutes to an hour in a chair that cuts in the back of my leg or knee. I ve been sitting for 6-7 hours, 3 days a week, for the past 2 weeks while my husband is having dialysis. Tonight, it hurts when I put pressure on my leg while walking. Any idea what this could be?
