My guineas lump

Question
My guinea pig Fitch got a lump on his kneck over 3 days. I was wondering if it would be a cysts because it grew so fast, or either a tumor. Some people tell me to poke it with a needle and see if and fluid will come out. But I can't see it and I'm scared it would make his condition worse. Please Help me!

Answer
It is most likely a cyst, swollen mouth abcess or swollen lymp node. You will need to take him to the vet, do not drain it your self, this can cause infection and he will need antibiotics from a vet once treated. There is not much you can do yourself, this however is not likely to be a tumor, tumors grow slowly and tend to bring a lot more symptoms.
