This twitch was different

Hello everyone, I hope all is well with everyone that finds this post. 
     Today my daughter and I were at the kitchen table, she was teaching me how do make the plastic lanyard things.  Then I felt this strange tingle kind of (I really can't describe it any further than that).  I look over at my forearm.  It was twitching from my forearm, wrist and hand.  This was the first day that or the first time that a twitch has been that wide, and felt like that.  My daughter thought it was gross, she said it looked really weird because of the length it was.  Again, it disappeared as soon as I moved.  I just wish it would do this in front of the doctors. 
     My fingers on my left hand are also more rigid now.  With my hand, it's been going on for a good while, but now it is more often; just about everyday.  They get stuck and sometimes I do wonder if they will be able to move.
          Thanks for reading, God Bless.
