PLEASE HELP - LEAKING NOSE

i got a tonsillectomy and an adenoidectomy on 11/18 (had to be recauterized 11/25 and 11/28). recently i have been unable to drink without it STREAMING back out my nose. like not just a couple drops, a full STREAM. IT IS SO IRRITATING. for couple days i felt really great and had minimal pain when i swallowed and my energy was back up but now i feel like im going backwards. my throat feels sharp and painful where it wasn’t hurting before, any liquid burns the back of my throat and is difficult to swallow, and everything. comes. up. my. effing. nose.

is this normal??? does anyone know how to fix it??? will it go away??? please help im desperate
