I went for an mri today because I was almost positive that I have a blood clot, it was extremely painfull ,still is. There was no blood clot , blood flowed ok. So what is it? It started a week ago. Horrible pain around the knee. Then the pain area moved to 3 or 4 inches above the knee to the inner thigh and the top of the thigh. Some times I feel it around my kidney area,like it is a muscle. With my knee getting most of the intense pain right now. I have no fever or any other symtoms except for being very hard to walk or move around. I am using a walker to get around with lots of pain. I am going to go to the emergency room if things don t gewt better. The thought of all that moving around is not welcome. What do you think?
