My son is almost 18 and has suffered with tics since he was 12. He is currently in a phase of a horribly loud and frequent yelping sound. His doctor put him on Clonazepam and things seemed to get better but last week they got bad again. The doctor dismisses my questions about testing for strep and PANDAS. A IGG was completed last year showing high numbers for wheat and eggs. I have tried to eliminate this from his diet but he is a teenager and defiant to all of this. Is there anyone out there who is dealing with a teenager? Anyone know of any good doctors in the Minnesota, North Dakota, South Dakota, or Wisconsin area that is open to testing for other possible triggers? Also, he is currently taking an antibiotic for acne...could this cause any problem? Please help! I feel so alone and almost dumb when it comes to all of this. His tics, in the past, have always come and gone but this one seems to be lingering what seems like forever. My son is so angry.
