hope she's better in the morn hun... when all else fails jump in a luke warm shower with her and the icy poles are hydrolite, taste like crap but great for dehydration!
If your worried no harm in going to the hosp, if you can even if she's hot and in your bed try and keep a sheet b/w you, your skin contact will make her warmer and her warmth will get annoying.... hun your doing everything right.
I remember when A had a reaction after her needles and was hih temps etc. at 11pm i was in a cold shower with her and then sat in my room watching wiggles eating icypoles and rubbing her with a cool cloth
