My son had a febrile convulsion on Tuesday his first one ever. The doctors thought he may of had an infection but his throat and ears were clear so were his bloods and his urine and is totally back to normal today. I'm a little confused as to why it happened as it came on all of a sudden he was happy and playing and then had the convulsion had no complaints of feeling unwell. There is epilepsy on my partners side of the family and im worried that it may be the start of that.
