The past couple of days, I have had weakness in one of my hands. It came on suddenly and I didn't think much of it. My pinch grip is suddenly almost non-existent. I noticed because I always open packages for my kids and suddenly I feel a weird feeling when I pinch my pointer and thumb together and can't open things. I looked up some possible causes because it bothered me and it said ALS. Now I am full blown panicking. I'm a 30 year old female.
