My dr has done alot of blood work that has all come back normal so far and she has sent
me for an EMG, which I had done yesterday. The dr that did it told
me that my nerves are fine, but when he tested the muscles in my left leg, he said that there is some crackling. When he does the test, you shouldn't hear anything but when he did mine, you hear the crackling. He didn't say anything else, other than more blood work needed to be done. What could it mean?
