I have a question hope someone can help me please. I have been to this site alot but not for a long time.I started twitching 3ys ago but it has gotten better over the years. I have had every test known and nothingI had 3 EMGs normal. Here is the Question I have a Buldging disc in my neck putting pressue effect on my thecal sac whatever that is, but anyway I have been having problems with my left arm it gives out on me when I use it alot or carry heavy things it shakes like crazy I have to rest it for awhile for it to be normal again soI have been in PT for it. My orthopedic doctor recomended an EMG so I got one today and have been freaking outwhen the DR. told me the results it showed positive sharp Waves and Fibs on my left side my neck I said thats bad he saidit meant that there was nerve irritation. I asked him if it was you know cause he had my history he said it could be comimgfrom my neck has anyone else ever had this? I am freaking out I have only known fibs and sharp waves to be nothing butbad and to have both I am so scared he did not see any fascics though. Am I done for? He told me he didnt see ALS so dontworry but I cant stop and I thought I was past the worry part . Thank you,Anna lee
