Hi everyone...I am having an EMG next month. In the beginning of February, I had an unexplained fall while walking to my son's school. Since then, I have not had any more falls, nor have I noticed any weakness. Last night, however, I woke up with a horrible burning pain in my right heel. It has yet to subside. I know this can be a symptom of plantar fascitis, but my heel hurts the most when I am not standing on my feet, which would be the opposite of plantar fascitis. I have had muscle twitches for years, so I am not to worried about those, however the heel pain has me quite concerned. I was looking through some threads on here and saw quite a few that mentioned heel pain. Would anyone be able to tell me if heel pain should be a concerning symptom? Is this something that is common, and if so, does it tend to present early on in the course of the disease? Thank you so much in advance for taking the time to read this.
