Heat boil

Kiele has got a heat boil i guess.. on her left side of her forehead. The place around the boil has turned red and slightly swollen. – Yesterday we gave hot water fermentation on doing that the boil broke open.. we thought that the swelling and redness would reduce by morning.. but the same still exists..

Can any of you please let me know if there is any home remedy that I can try on her. This evening planning to take her to the doctor. I would prefer home remedy rather than doctor’s medicine. Please let me know what has to be done.
