This is a little off topic but may be worth exploring. Sudden onset of tics (motor and vocal), OCD types of behaviors and anxiety can also be due to Strep. This is a condition called PANDAS - Pediatric Autoimmune Neuropsychiatric Disorder Associated with Strep. My son has this and has struggled with vocal and motor tics a lot. He does not have active symptoms of Strep in his throat but it is somewhere in his body. There is a discussion area on ACN Online for PANDAS which may be worth exploring. There are also some great websites with information such as
http://pandasnetwork.org/. There are some tests that can be run to help see if it might be an issue (ASO Titers (strep antibody levels in your blood, AntiDnase B test). PANDAS is not widely known or acknowledged in the medical community. It is slowly being accepted and acknowledged because it is a recent discovery. It is real and there are treatments to help put it into remission. It took me many years to figure out what was really wrong with my son. We have worked with a good Naturopath who did not do a lot of homeopathy. We have found many allergies and changed his diet significantly which help reduce his symptoms significantly as well as many supplements. We have recently started on some homeopathy through his pediatrician and it seems there might be some side effects but it is too soon to tell for us. PANDAS is caused by the antibodies produced against Strep which attack the basal ganglia in the brain. These patients are usually highly sensitive to Strep and may not always show symptoms of Strep (as in my son's case). Hope this is helpful and that you find out what is best for your child. May God bless you.
