Yes, she's still on painkillers. She's on tramadol and carprofen (along with Clavamox as an antibiotic). However, she was acting fine all day yesterday until last night came around. And it was definitely a very hormone-like reaction. She was trying everything to get us to take her outside because she wanted to go around the neighborhood to mark. She's done this before. But before, she was actually in heat. It just worried me because she's supposed to be resting, but instead, she was incredibly stressed/anxious for hours over this.
The behavior started around 2am and lasted until 5am. Nothing I could do would distract her or calm her down.
