Guinea Pig hurt?

Question
So I was carrying my Guinea pig on my couch and we were fine. But then this noise appeared and she got scared and got off my lap and she freaked out. I don't know how but she managed to jump off my couch and started to run like crazy. I catched her and put her back in her cage. After that she started to sneeze a lot and having a weird wet breathing. She also almost right after putting her in her cage she layed down and got up and walked a little but then layed down at the same time like if she was tired or she hurt her legs when she jumped off my couch. So I don't know if she hurt her legs after that jump and what about that breathing? Did something happen to her?

Answer
It's possible it was just fright that caused her to run like that. I would suggest you just leave her alone and quiet for a day and see if she doesn't return to her old self.

Guinea pigs are faster than one would expect, given their pudgy little bodies and short legs. It's unlikely she suffered a leg injury, or she would not use the affected leg. I've seen many a pig take a dive right out of someone's arms and land hard on the ground.  The most typical injury is often a broken tooth. However, since their teeth never stop growing they are able to replace it quickly.

They also make strange sounds on occasion that sound like they're wheezing, but in fact are not. The best indicator of how she feels is whether she is eating and drinking normally.  If she is, then she is okay.
