Parasthesias have nothing to do with ***. Perceived weakness is common with BFS and anxiety. I have experienced everything you are talking about. The stuttering thing is terrible. Once you start fixating on your speech, it's hard to stop. And being aware of it changes the way you speak. My mouth would get dry and my tongue thick...S's, CHs, and Th's would sound weird to me. I would stumble on words especially when nervous. All my symptoms get better when I deal with the anxiety, get sleep, lower my caffeine, and take care of myself.
