My ds (aged 5) has had tonsillitis since last Friday. He is very poorly bunny, with high temp, horrible snotty nose, tonsills like golf balls covered in white yuk and stinky breath. I took him to the GP yesterday and he reluctantly gave him antibiotics (Penicillin). My question is how long is this likely to last - I have no experience of this at all and neither DS or DD have ever had tonsillitis before. When can I expect to see some improvement (and therefore get some sleep/peace and quiet!)
