I've recently had surgery to get my tonsils removed and for pain medicine they gave me the oxycodone pills. The pills are very difficult to swallow since im all swollen so ive had to crush them up or cut them up into tiny pieces to take them. My sister had the same exact surgery done to her 3 years ago and they gave her the Hydrocodone pain medication in liquid form. She gave it to me to use so i wouldn't have to take the pills. The hydrocodone expired 08/2015 but i read that it would still be fine to use it. Even though they are diffrent drugs, they are both used for the same purpose. So I was wondering, could I still use the hydrocodone?
