My daughter has tourettes. She's 16 and just over the last few months has developed motor and vocal tics that have taken away her ability to enjoy her teenage life. It's been a nightmare. We are seeing a natural doctor and chiropractor who has helped us find her food sensitivities, chemical sensitivities and metal sensitivities. Today I noticed that she has a severe tic attack while I'm driving her in our car. She starts talking about feeling nauseous, and that she can feel them starting in her belly. From there her tics become out of control, not that they're ever in control. It takes a good 25-30 minutes after she gets out of the car for her body to settle down. Has anyone else experienced this with their child with tics? What could possibly be causing these tic attacks in our 2003 Ford Explorer? Any help is greatly appreciated.
