I have had two EMGs in the last several months. In the first performed on my left leg it showed some reduced recruitment in my iliopsoas muscle. In the second EMG perfomed on my right leg it showed "slow firing of motor unit potentials in most of the muscles tested and the intermittent activation of motor unit potientals in most of the muscles tested" are these things to worry about? If so, what illness could they point to. (other symptoms include motor weakness in all extemities; twitching, shaking, and muscle contrations in all extemities and face; trouble swallowing; urinary incontinence; visual changes; and extreme fatigue)
