I Have An Aching Pain Down My Left Leg For Over A Month And A Half. I Have Had A Doppler Done And No Blood Clots Have Been Found. It Hurts More When I Sit Or Try To Extend My Leg Out. What Could Be The Problem?

It could be a pinched nerve or something like that, are you getting cramping? I am wondering because you could be low on potassium and would benefit from eating a banana or potatoes. I suggest you go and see a chiropractor about it, and see if this might help you out. Hope this helps, good luck to you.
