Sorry this has got abit long.
DS is 3.4, really really healthy, hardly ever go the doctors, last time until the last couple of weeks was prob over a year ago.
Anyway about 3 or 4 weeks ago he fell, just minor, couple of tears but soon distracted. He had a bump and red mark on his head so i was mainly concerned about that at time but i noticed the next day he also had a small graze on his thumb, no probs he seemed fine. Anyway the graze went all manky so went to doctors who gave us cream as said graze had become infected. Cream didn't seem to be working so went back and was given oral antibiotics. At this point he also had a few spots which doc said was linked to the infection in his finger.
Finished the antibiotics and finger more or less cleared up. Whilst taking the antibiotics he got a red sore looking patch on his nipple and then about a week later got a really red sore looking patch at bottom of back which looks sort of like a red sore looking burn mark. Went docs on monday and said it impetigo and has given oral antibiotics again. He's taken them for 3 days and it doesn't seem to be getting any better, if anything it looks worse and he's got quite a few more spots coming and the patch on his back just looks awful and is now weeping, its at least a couple of inches across. He had impetigo once before but that time he had more spots and it looked more like chicken pox.
In himself he seems perfectly fine, no signs of illness.
Anyway should i go to docs again tomorrow/ Friday or should i wait until he's finished the course of antibiotics? If i don't go by Friday then would have to leave it to monday which i think is a long time if its no better- but like i said above DS is really really healthy so maybe i'm over reacting as i'm not used to him being ill.
