So i have Bell's palsy which is half of my face is basically frozen anyway they gave a steroid I've been taking it daily (obviously) but i also have been taking oxy for my pain (i have stitches from giving birth and i cramp real bad ) so i take them together every time i take it my face gets blotchy red itchy spots and my tongue feels like its going down my throat but it looks it's normal size .. Also my right eye (the side that is frozen) won't shut like unless I'm sleeping i can't see out of it either i close my good eye and all i see is "cloudy fog in my eye). What is this ? I've been told all my life the only medicine I'm allergic to is salfa .
