^ Hmmm, I'd keep an eye on her and take her into the vet asap if you see her getting worse/being odd.

I would have RHPs and belly heat/flexwatt in vivs if the room was kept colder, but I've had no problem with just belly heat in a viv (snake room kept at 80). Doesn't make sense to me why a snake couldn't thermoregulate themselves/digest properly with belly heat if they have an appropriate hot and cold side?

If the room is colder I would do both, but I've had no problems with digestion/thermoregulation/RIs with any of my boas in both vivs and tubs with only belly heat.
