Pain in right leg from hip to toes, my right toes are so much colder then my left. could it be sciatic nerve?

Not likely: This sounds more like a circulatory problem, such as a blood clot, and if so, you need to be seen promptly to evaluate and reverse the cause. Your leg could be at stake! Good luck.

Sciatica: From the description you have given it is entirely possible that you have sciatica. This inflammation of the sciatic nerve. It usually gets trapped coming through the gluteus muscle. Sometimes I have seen the pain lessen by using an elliptical trainer. Anti-inflamatories can also help relieve the pain.
