My DS (4) started off with a really sore throat about 2 weeks ago, took him to the doctor who said his throat was all red and inflamed and prescribed antibiotics for 5 days, after the 5 days he picked up a lot in himself but was still saying his neck was sore so I took him back to the doctors, they said his throat was still abit red but didn’t look infected now and gave him 5 more days of antibiotics. Today is the last day of them antibiotics and again tonight he said his neck is sore. I’m worrying now that something more sinister is going on with it taking this long to clear up
