I have a rare type of TS tic called a 'blocking tic" such that it prevents me from speaking. When this is going on I feel spasms in my larynx (vocal cords) sometimes along with a somewhat painful sensation. Have any of you all run across this before? It's similar to what is known as a 'negative tic' a tic that keeps you from moving some part of your body such as your arm. Anyhow, this is an annoying symptom that I'd really like to get under control.
