If u had a 100% blockage in your leg your toes turned black you had emergency surgery to fix it 6 weeks ago. Still have toes they seem to be alive there is some black spots. But u have pain like heat, burning, stinging. Enough pain that u can lie down, that u need to keep leg down like when u sit. Question is: could there been nerve damage and will get better. Thank u
