If she is taking naproxen she cannot take ibuprofen, I have a union spinal break to the leg the pain I'm in most days is unbelievable and my ankle goes double the size of hers, im given tramadol naproxen morphine (I know she can't take) and amitrptailin never have they offered me codine in the last 4 years, gabbapline yes but never codeine it seems a strange drug to give out for a sprain, it is normally paracetamol and rest, they have told me paracetamol is the best thing for pain relief and it has been given to me by drip before at hospitals (mines actually broken still even with the nail going through the bone to hold it in place) due to pain but never codeine, its all very strange and surely if they have seen her stomach they would ask if she was pregnant and do a pregnancy test just as a safety measure before taking codeine
