I have had a very nagging pain in my R upper outer thigh now for several years, never had anything diagnostic. I think it is directly relational to what kind of chair I sit on or whether I sit with my left leg up under my right leg. My minivan seat is deeper than my husbands car and it hurts more in my car. I also think that the more it hurts the more pins and needles feeling I have in my lower leg. So tomorrow I do an MRI!
