Hi L., try keeping baby upright after feeding. Remember baby doesn't have our clearing reflex, baby may have gotten some up her nasal passage. If it continues take her to pediatrician. My 11 old was like that, it was like the excorsist. LOL. Try less aggressive burping, i used to forget how easy baby needs burping, and next thing i knew i was pounding on them without knowing it. Good luck...
