Help! How do I stop my painful tics?

I've not had a lot of success with this myself, but a close friend of mine can channel really disruptive tics (like screaming) into slightly different ones (like opening their mouth but not making a noise) - perhaps there's a similar but less painful action your can redirect your most painful tics that will still satisfy the urge. Also seconding the comment that medication can sometimes be helpful

I don't have crazy tics but I've had a couple that were detrimental and honestly I never found a complete solution, it was just a matter of figuring out what triggers were, what state I was in and how I could affect that to make the tics less prevalent. Not sure if im of any help but it's very dependent on your mental state, maybe some kind of meditation could be helpful?
