I rehabilitated a very sick boa once with far worse problems than you describe here. I would boost her temperatures a little, but keep her humidity normal (peruse our caresheet if you have questions about the temperature or humidity ranges a Ball should be kept at) Rest, heat and sanitation are of the utmost importance for now. Don't handle her more than you need to, and keep her warm, and her cage spotless - especially her water dish. If you are worried about sanitizing hides, use cardboard boxes (cereal, crackers, etc,) and simply throw them away once they are no longer any use to her. You can usually buy a temp gun on amazon, or at a local herp show for $20-$30. If humidity is low in the cage, you will need to replace it with a better cage (best bet long term) or fix the lid. reptiles need very little ventilation, in fact, ventilation causes more problems than it solves. I regularly keep snakes in unventilated boxes like these for quarantine. They are marvelous for keeping heat and humidity in, especially in conjunction with a heater beneath them. Just line with something disposable (paper towel, butcher or news paper) and change daily.
