I posted the other day about my sons cough, well it turns out he has a chest infection and throat infection, we had him at A&E last night for rapid breathing and he was given an inhaler and antibiotics, we've been told to keep an eye of course in case breathing becomes bad again but he's had 3 doses of antibiotic, 1 last night, 1 this morning and 1 at lunch time. This afternoon he's had some diarrhea, is this usual with chest infection? He's never had a proper chest infection before (always throat or ears or colds) but he has had many antibiotics for ear infections before and it's never given him diarrhea before? It's just amoxicillan which he's had before. He's not eating much at all, few mouthfuls a day for the last 3 days but drinking enough. I've tried googling to see if chest infection usually can cause stomach upset but haven't been able to find anything. Anyone any experience with this? Thanks.
