I have swelling in my lower leg. It's very painful, the pain goes down in my foot and up to my knee. Not all the time in all areas but there's always pain somewhere in my lower leg. I've had an Ultrasound and no blood clot, the xray didn't show a break. I'm supposed to have an MRI done but I don't have insurance so as soon as I can I'm having that done. I just don't know what is wrong. There is a knot right above my ankle bone on the inside left of my lower leg. It's painful when pressing it. They have ruled out edema. The swelling is still there even after I have slept all night with my leg elevated. Anyone have any ideas, suggestions, etc?
