My 8 year old child had sudden onset of tics, hyperactivity, and high emotions about a month ago. Our doctor immediately suspected PANDAS and did a throat culture and bloodwork. His ASO titers were over 400 and his throat culture was positive. He prescribed 400mg Amoxicillin 7.5ml twice per day. Except for occasional eye ticcing, everything else went away after a few doses. We were thankful. The day he stopped antibiotics he got a fever and flu-like illness that lasted 5 days. He had another throat culture 2 days after stopping antibiotics that was negative. Exactly two weeks after he stopped the antibiotic his tics returned. We went for a throat culture and since it was the weekend the doctor gave us another script for Amox. to take if things got worse over weekend. They did get worse (although not as bad an original episode) so we started antibiotic. Come to find out the culture was negative. Doc originally said to stop if negative but since we stated his symptoms improved, he said to do one dose per day until it's gone. My husband is very concerned about keeping on the antibiotic without an infection and has a message in to ask if we can stop it and start colloidal silver and other natural remedies. He and I are very divided on the issue. Any thoughts on what to do and to keep the peace?
