I have symptoms of peripheral vasular disease, pain in right calf and foot goes numb whenever pain is there. pls advise, as no neuro docs in our city?

PVD and numb foot: You seem to be young for PVD. PVD causes claudication pain, not numbness. Numbness is usually a nerve that is being compressed. I wonder if you suffer from PVD or possibly radiculitis? Vascular and neurological studies can help differentiate the two conditions.

Sciatic nerve irritation.: You are probably a little young to have vascular disease. Much more likely you have some lumbar disc disease with pinching. When you pinch the nerve you may get numbness, weakness, pain or loss of proprioception. That means your foot doesn't feel quite right when you put it down. Try some low back exercises. You can find lots of low back exercise if you Google. I think you'll also find those on YouTube. If you are overweight, it will also benefit you to lose weight.
