Just went through this with my daughter. Get his tonsils out NOW! DD had strep infection off and on for years and yet I couldn't get them to take her tonsils out. Well, finally she was so ill I took her to the ER and they discovered once again it was strep (the dr office tests were negative). So we finally got her tonsils out. She continued to get sicker and sicker. After a lot of Dr visits and ER visits and $$s spent we find out she has rheumatic fever. She will be on antibiotics for the rest of her life and she is in so much pain 3 months after her tonsillectomy. I'm hoping the pain will eventually go away. She is so sick she had to drop out of high school. Luckily it hasn't damaged her heart yet. We hope we caught it in time.
Please get his tonsils out. I think strep has become resistant to some of the antibiotics and this is causing a problem. The strep lives in the infected tonsils. DD even had tonsil stones!!
