Hi there,
I am sorry your cat has this trouble.
It is most likely an abscess:

It is going to keep draining and reforming due to bacteria in the airless environment.
Ask your vet for a script of clavamox or clinamycin BID for 14 days.
Since it is hot your girl should be reseen today.
Please let me know how she is doing.
Best wishes for her
