This is not a fever thing like Chiccadum's but it shows that it's not just locum services who let you down.
When my DD1 was 4 he got an awful crack on the head (tripped up running around DH's office and fell into a desk) which left him with a split forehead - the cut was over an inch long. We took him to the treatment room at the local HC, which normally gives excellent service, but despite his age he was made to wait over an hour until the duty GP (female) had time to see him. The receptionists were apologetic about this.
This was on a Friday. He seemed OK when he was eventually stitched up and went to Grandma's on the Saturday to spend the night.
When he came home on the Sunday evening his forehead was like Herman Munster's. (Grandma is a bit vague about details like that and apparently he had also bumped his head a bit on Saturday night.) I immediately rang the HC number, which at that time automatically transferred you to the GP on call. Guess who? The woman who had kept him waiting an hour. She told us to bring him to the Treatment Room in an hour's time - she happened to live literally across the road from us, but when I said "but you are just across the road, why can't you come here?" she threw a hysterical hissy fit and wanted to know how we knew where she lived. ("Because you live across the road" wasn't a reasonable answer, apparently.)
We happen to be on friendly terms with our GP because we have kids of a similar age who went to school together, so we went to see him at home and he referred us to the "local" hospital (15 miles away) where DS was put on an antibiotic drip because the stitched cut was infected...possibly because of being left open, in the HC, while we waited an hour for her, who knows. He was in hospital for several days and missed the first couple of days at school.
Anyway I didn't like her then and don't like her now and avoid her whenever possible. I wanted to make an official complaint about her behaviour on both counts but our GP told me that he would be held responsible for what was done by his "locum" and I didn't want him to get into trouble so I let it go. (susanmt, is this still true???)
(I did see her once subsequently - at well-woman clinic - mentioned that I was considering having a 4th child and was bollocked for even thinking about it after 3 caesarians. Apparently she was having trouble conceiving. Not a good GP by most standards I think.)
Have just queried details with DH...he can't remember exactly what happened after the hissy-fit phone call - he thinks she did cross the road and see DS here and refer him to local hosp. Mind you it was over 10 years ago!
