I am 16 Years old and have a weird twitch in my arm and have the need to clack my teeth together and blink my eyes at the same time and if i don't get it perfect i will do it multiple times until I do, I don't have any real vocal tics or anything. When i twitch it's almost like a cough, i feel the need to do it become stronger and stronger until i almost have to, it is hard to resist. No i do not do any drugs, or smoke. The tics i experience i had a year or so ago but they went away, so i thought nothing of it but now they have slowly came back. I'm confused as to what this is so any ideas would help.
