Suggest Medication For Pain,numbness And Tingling In Legs After Placing Stents

I had 2 stents placed in my left leg's artery a year ago. The symtoms of my calf hurting when walking and my foot feeling numb and cold has returned. In addition, I have pains on my inner thigh ( where the oclusionn was) and upper thigh. My right leg has started a "tingling and numbness" on the outer thigh. How serious does this sound?
