Yes - it can do - for me at least things have more or less gone.
I have kind of lost track of time now - the sypmtoms seemed to last a lifetime, but I think it was probably worsening over a year or so and then it started to get better. I did post on here - but now i can't remember the exact time scale - which shows how little it concerns me now..
Now it is getting on for two years after that horrible day when my thumb twitched all day by itself, I am more or less better. I have many days entirely free of twitches - it comes back with viruses on a minor scale and when I had a trauma when a friend died - it came back for a few days really badly.
I had quite severe symptoms - particularly pain and some fatigue. Now i do all sorts of sports again and am generally happy.
But the key for you is to learn to live with it and be happy anyway. get yourself properly checked out and then move on.
best wishes
