Hello, I am new to this site as well. I was just like you a very healthy active person. All the sudden i had problems that have my life filled with anxiety. I found out after my EMG that i have benign faciculation syndrone. which looks like ALS but thank god isnt.*edit*, i cant leave links yet but you can google *edit* to find the page it is very helpful. Those diseases are very rare and there is a good chance you dont have it. I can empathize with you. I have myself so worked up over this whole thing it consumes me. Hope all goes well.
