Why can't you tell your medical doctor? He certainly would NOT laugh at you! And I'm sure some forms of Tourettes can lay dormant for awhile and then show up. You would have to ask a doctor tho.
So talk to your doctor about it. Believe me,, he's not going to make fun of you. I promise you. Just tell him that it is serious and really bothers you!
God bless you my friend, and PLEASE let us know? We really CARE! Hugs, Lee
