When this is noted as a symptom of different neurological disorders, is there a certain extent to which it's referring to? I don't think I feel weak, but then my mind sometimes plays tricks on me and makes me wonder if I do because I'm paranoid I have something bad. I often try to do things involving my muscles to sort of test myself such as, squeezing a fist, doing exercises, etc. I don't think anything has changed, but then like I said, my mind likes to play tricks on me and thinks that even though I can make a pretty darn tight fist, it tells me it's just not good enough. (Hypochondriac here, fyi).

Like with MS, for example. Is muscle weakness pretty apparent and easy to notice? If you've had it, how did you experience it?
