Hi, I haven't posted on here for a while but I figured maybe someone could help with the current situation. My guinea pig Popcorn has struggled with chronic gas episodes for years, but this gas episode has become odd. She was having it for over a month or so, but it became worse and now isn't going down at all despite the constant medications she's been on for it. Yesterday, however, I noticed on her left side it was especially hard. usually, gases are hollow and can be poked at, but the gassy part on her belly is hard and does not feel hollow. When i touch it it's firm, heavy, and can''t really be fully pushed so the gases go to the right side (which I can always do with gases). It's on her side but also towards her hip/lower belly. It does not seem to hurt her when I touch at it. I'm starting to suspect it might not be gases, but it doesn't fully seem like a lump either. It looks completely like gas until you touch it, plus it isn't exactly its own shape. Another guinea pig who recently passed away did have a lump on her bottom side that turned out to be an extremely swollen kidney, so I am not sure if perhaps it could be a similar situation, I really hope it's not. She is still being herself and eating/pooping well. The earliest vet appointment we could get is three weeks from now, but I am stressed and wondering if that's too long wait. If anyone could offer thoughts I would really appreciate it.
