I have had a numbness sensation in my left forearm down through my two fingers, pinky and ring, for just over three months now. I assumed it was due to a pinched nerve and hope that the feeling would subside over time. Well, it hasn't. Now, in addition, I have the same feeling in the top part of my leg from the knee to the hip. And on occasion feeling a horrible burning pain just above the left knee. I have seen two doctors and both have recommended MRI's, something which I plan to do as soon ASAP. One doctor mentioned the possibility of a tumor, seeing as though the numbness was not restricted to one area. Has anyone else had this type of problem, and if so, what was the result and prognosis?
