So I took her to the ER the Monday night because she started walking in circles, and they did blood tests and an exam and ruled out anything life-threatening (poisoning, stroke, etc.) and also ruled out an ear infection or vestibular disease. So two nights ago she started doing the same thing again and I called the ER and they were swamped and pretty unhelpful but told me there was probably not anything life threatening so we went to bed. Now she's doing the same thing again and I'm worried about why this is a pattern, so I guess I'm wondering if you can help me decide if this is something I need to be really concerned about or if there is a non-scary explanation. She doesn't seem disoriented or to be having any balance issues, and hasn't been lethargic or changed her eating/bathroom habits at all. She is still playing, jumping up on stuff, etc. as she normally does, but it just seems to be that she needs to walk around in circles at night and gets very easily rattled...it's almost as if she's pacing to find something or survey the room rather than out of confusion. Help!
