My son has had on going infected toe with ingrown nail he has 2 lots of nail surgery and 5 lots of antibiotics his last antibiotics was flucloxacillin a week ago for 2 weeks he now has another course for 5 days is it ok to have it this many times ? it makes him feel really sick apparently at the surgery last Tuesday the infection had gone but the toe is very red since and they think is infected again. Has anyone else used flucloxacillin this many times any advice thank you
