I tried gently cleaning the outside, but I'm concerned about the swelling

Hello I have a 5 1/2 year old female guinea pig whose private area looks swollen and has little brown, crusty buildup around it. I tried gently cleaning the outside, but I'm concerned about the swelling. She's currently eating, drinking, and pooping normally. She is acting like her normal self, I just am worried about the swelling. I got her from PetSmart and I'm not sure if she's spayed. I always make sure to care for her and give her everything she needs. Could a veterinarian or anyone experienced with guinea pigs please look at this message and let me know what to do. Thank you!

Hello, sorry to hear about your guinea pig. Is she housed by herself or with another guinea pig? Ovarian cysts are common in older female guinea pigs and she should be evaluated as soon as possible. It's likely she is not spayed.
