I was feeling good up until recently. Very few fasics. Little-to-no pain. Now, I'm feeling bad all over again.Before, I wrote that I have a odd nerve issue: my left heel gets a prickling sensation when I pass a stool. My neuro ran a lumbar MRI, and found nothing; said it may be a nerve root irritation. This issue is still with me, especially when passing a stool or wiping after. After this issue occurred, I felt this heavy, weak spot above my middle toe on the left foot; it comes and goes. Is this a nerve ending? Is this a failing nerve in that region?When I got up this morning, my upper left arm felt like I had a piece of tape stuck to it occasionally. It felt very tired when I was combing my hair when I was getting ready for work.I had 2 EMGs; the last being in July 2013.Should I get another EMG?I leave for vacation on April 24th and I don't want anything bad to happen when I'm away.
