My son is four and has had strep 5 times since September(in addition to ear infections and pinkeye) and has alternated medicine each time to avoid building up a resistance. He recently had strep and finished his antibiotic. Within the week he was back on an antibiotic and this week he still has a fever, achy bones, lethargic, stomach pain, swollen glands, and white spots in his throat. The chest x-ray and mono came back negative. I'm wondering if anyone has any ideas as to why he keeps getting so sick. As of today he will have been on 10 days antibiotic (with only 6 days off previously) and now has been prescribed for another 10 days. He will be going to an ENT in two weeks but II am really concerned, please help with any information.
