Hi, I'm 17 and felt my first twitch about three months ago, I am still experiencing twitches at random for example I might have one in my foot, then in the opposite knee, then to my neck. I have talked to my doc about it and he thinks these are related to anxiety as in the past I have suffered from severe anxiety. I have also noticed, my left hand (I am right handed) has been kind of weak after I noticed one of its muscles is a bit smaller which I think could be due to an injury I sustained on that arm. What happened was I accidentally stabbed myself on the underside of my forearm a few months back deep enough to hit the tendon controlling my thumb. I know I might sound silly but I am freaking out right now, thanks for reading.
