No post op instructions after surgery on 11/22

I had an Evans osteotomy and a few other things I can’t remember the name of to give me an arch and lengthen some areas. The doctor put me in a boot and told me to elevate and take meds. Now that I’m home, I realized I’m not sure if I’m supposed of elevate all day even while sleeping or just sometimes. The boot feels really tight and I’m not sure if I could loosen it or if that’s just the swelling. I’m in a lot of pain and the doctor didn’t give me any paperwork to take home to say if I could ice it. They don’t open till 11/25 at 0900. Anyone have recommendations from your own surgery?
