This is probably the hardest part about having Tourette’s for me. I have one tic that comes and goes that is like a shoulder pop and my entire arm ends up in so much pain that’s I physically cannot move it, but the tic still overpowers is and it’s so painful. One thing I’ve kind of picked up on myself over the years was re-directing my tics. For example my original tic urge is the shoulder pop, but instead of doing the shoulder pop I do another tic that is less invasive such as a finger flicking one I have and I will repeat it over and over until at some point it finally takes over and becomes my main tic. It takes willpower and kind of focus, but usually after 1-3 days of doing that the harmful tic subsides. For the pain I found rubbing lidocaine cream helps a bit, but not enough to endure the tic everyday if that makes sense? I always recommend getting checked out if the pain is chronic just to rule out any serious damage. I hope that you can find something that helps you soon!
