the way you are explaining, your problem calls for proper and regular treatment till they are totally cured , occassional application of ointments
may not help you out of your problem. Get your blood sugar also examined. Off hand i won't suggest any local application but would suggest you to start herbal treatment which may take about a month or so but will offer you permanent cure.
mahamanjishtha arisht 2 tsf mixed with equal water &
tab. gandhak rasayan 2 BD i.e morning and evening one hour after meals
haridra khand 500mg i.e. half tea spoon & tab. Allerin 2 BD at noon and night time.
avoid sweets and heavy meals and don't touch the area with dirty hands time and again.
