I love doing EMGs but does anyone else get frustrated by the fact that the information you need to put the whole picture together sometimes just isn't obtainable? Either because the patient can't relax, has too much pain, or has too much swelling/SQ tissue. Hell, even in a young healthy person, it can be near impossible to get some of the LE sensory nerves. I find it intellectually frustrating. Like those X-files where you're waiting for the mystery to be explained at the end, but then it isn't.
