If abscess is there , it needs to be drained.. Homeopathy will not cure it.. You need to visit Pediatric surgeon.. They might do few scans to know the extent of abscesses and incision and drainage will be done..
If you are sure , it is an absecess than do not wait. It can become worse and if extending deep inside, might need a bigger surgery.
Do not ignore it.
