The tics are the only symptoms right now. As far as I know I don't have any thing I'm allergic to, but I guess getting some type of allergies test done should be my next step. I started a yeast free diet along with taking a candida cleanse because I read that a overgrowth of yeast can cause some tics. And that some people have had positive results after this treatment. But getting a food allergies test makes a lot of sense. I do know that after a cold my tics are dramatically increased.
