For the past couple of days, I've been feeling the greatest "perceived weakness" I've felt since this started. A couple of days ago, I noticed that my left index finger was tremoring, and since then, it feels weak and "floppy" to me. I've tried testing it out on various things, and it seems to "pass" -- I tried to repeatedly catch a Coke bottle with just my thumb and index finger, and I never dropped it; I opened the door to the post office with just my index finger; I grip my backpack with only the support of my index finger and haven't dropped it -- but a few events in day-to-day life just scare me. I dropped a piece of paper I was holding in my left hand yesterday, which never happens to me; when I went to pick up my glasses this morning after waking up, my index finger felt "off" and "weak," and when I tried putting on my underwear, the left side slipped out of the grip of my left index finger. So a crappy start to the day, and I'm freaking out already. I usually like to wait a little bit.I'm just worried because this hasn't gone away, and this is the area of my body where the twitching started. Oddly, it's also the area I've felt the strongest up until now... I also notice that my left index finger seems to have more "dents" in it than my right index finger, but I don't know if that was always the case. The muscles just seem much less defined (I'm right-handed, by the way).
