It sounds like an ear infection. She will need antibiotics for that, so until you can get to a vet, supportive care is what you can do. Metacam is fine, gas drops won’t harm. Keep her warm and if she doesn’t eat enough on her own, you’ll need to syringe feed her pellet mash or CC.

I missed the part about Famosan and Degan. Degan is fine, it’s metoclopramide, a very good gut motility drug. Famosan is also fine, it’s a PPI meaning it helps against too much stomach acid. It can be given with Metacam to protect the tummy, because Metacam can be hard on the stomach lining, My Bam was prescribed a similar drug (ranitidine, Zantac) to take together with Metacam.
ETA: Pumpkin is beautiful!

Many vets will give Panacur, which is a med for EC, AND an antibiotic like Baytril, in case it’s an ear infection, to try to treat the head tilt BEFORE any bloodwork/test results are back. You would also want to give Benebac, a probiotic, to protect against bad bacteria in the gut from the antibtiocs, and Metacam to reduce inflammation. It concerns me that the vet hasn’t given you any meds while you wait for test results, especially since Pumpkin has progressed to rolling. To protect her, keep her confined to a small place, and put rolled up towels on either side of her. If she can’t eat, you can syringe feed her Critical Care, a powder recovery food that you mix with water and make into a slurry.

I would definitely push for meds instead of waiting for bloodwork. Every day with no treatment matters- with treatment, your Pumpkin can make a great recovery. Please keep us posted! I hope Pumpkin gets on meds and starts getting better very soon!
