Short/long term: In the short term you can apply a warm compress near the site that should improve local circulation & self healing. It is likely there is a fistula or cyst in one or both sides that may eventually need removal. An ENT can assess this & proceed if needed. You may want to have her regular doc see it as they could help decide how to proceed.
