broken leg

hi everyone! im a new bun mom and recently last week i saw my bunny, marshy, limping on her left hind leg. so i took her to the vet and it turns out she broke her leg bad (pic attached). the orthopedic vet said that fixing her leg through plates will be quite challenging as bunnies bone...

She was limping so we brought her to the vet I don’t know if she needs medication for pain they didn’t tell me if i needed medicine for pain they only said it would heal it self and I don’t know what to do?
