Question

Answer 1

It needs to see a vet. Any abnormality on ANYONE'S body should be inspected by a doctor. Please tell your friend to bring him to a vet ASAP, as guinea pig health conditions are very time sensitive. It doesn't matter if he is acting normally either, guinea pigs hide their symptoms very well and can act normal up until the time they die.

Answer 2

Could be an abscess?
