I am sorry to hear about Patches. Unfortunately she has a problem we aren't going to be able to treat at home here. I would be concerned about the possibility of breast cancer given her history (being spayed as an adult, location of the mass). A vet exam is needed to examine the area, determine if it is a breast tumor, prescribe antibiotics if it is infected and discuss surgery.
