I have pain and a burning sensation that goes up and down my leg in all different areas. My Dr. did an ultrasound 3 weeks ago, but at that time I had numbness in my thigh. This is completly different pain. It is a burning in my thigh, hamstring, and calf along with pain (like a bruise). There is no swelling or discoloration. I worry because I already have chest pains because of GI issues so if it were a clot and moved to my lungs I don't know if I would know the difference in chest pain. Saw my Dr. 3 days ago and she said no need for another ultrasound because we did one 3 weeks ago and just to take so minor pain reliever.
