I (regrettably) had this procedure done a few yrs back on one toe but no recurrences. Looking back, it seems that the problem was only a minor ingrown nail but a major infection exacerbated by an immune disorder.
I would suggest trying differing antibiotic remedies like triple antibiotic ointment, Iodine, Tea Tree Oil. Check for any fungal presence in socks or shoes as this could re-infect the toes.
