Hi Foks T2 for 11 years always had pins and needle effect in my toes and feet recently it has started to appear in my left calf which is rather uncomfortable, I also in my left leg had the whole vein removed for a triple heart bypass, my question is do you think a Revitive Medic Circulation Booster would help as they are expensive, and the reviews on Amazon are mixed, has anybody tried one? did it help?
