abcesses on dog stomach

I have a 13 yr. old chihuahua she is 16 lbs. about 2 months ago she started having a lunp on her stomach it was hard at first then 1 week ago it got very soft. I had started her on lots of different herbs. this has not stopped her she still does her normal things eats drinks and go outside. I took her to a vet and she said since it already drained she should be fine. well my problem now is it keeps filling up with pus if it closes up, also she has hard lumps about the size of a quarter of a cupcake. I have no more money for a vet now, I am at my wits end please help///////////
