Two weeks ago I had partial knee replacement surgery. I was prescribed Ocycodone for pain management and to take 1 or 2 5mg tablets every 3 hours as needed. The the first six days following surgery a maximum of 1 tablet every 3 hours was sufficient. At the end of day six I endured 4 hours of vomiting finally call 911 as I was not able to walk to the car to go to emergency. My question: Is their a pain management drug that I could use in place of the oxycodone that may not cause vomiting or nausea. I am now just using Tylenol, 500 mg every 6 hours and could use something stronger.
