Lump on guinea pigs side

Question
My guinea pig nibbles is 2 years old and healthy from what i can tell its just she has a bump on her side the size of an eraser cut in half.  I noticed this a while ago but my dad just brushed it off.  Now i see a couple more by her nipples im really worried about her is there anything i can do at home as the vet is kinda expencive even so i know if it needs surgery or anything special. Please anser fast im really worried and want my piggies to have a long happy life thanks

Answer
well it is possible that they are ticks, though they sound a little large, if a vet is too expensive (which i understand they are a blummin rip off somtimes) then try taking nibbles to your local shelter or even breeder, we tend to be fairly savy with cavies and even if they are not abl to treat her they can probably diagnose her and give yu an idea on the price.
without a photo or a more indepth description i cannot really do much more, and these sorts of things are usually best dealt with in a face to face way.

but yeah try contacting s local shelter and or breeder, if they can help they will do so at cost.
