I had my PKR done in an outpatient setting and loved it. But I had already had 2 surgery’s on that knee in the same setting so the OS knew my ability to recover. I was put under general but was awake and home by 630 PM, survery was about 1230. I didnt start PT until week 3 (my choice).
Prior to my surgery, every thing hurt like you are, which confirms the need for surgery! But if you have been taking NSAIDs up until now to alleviate the pain then yes you will feel pain now for sure.
For the ice machine highly recommend using frozen water bottles (they last longer) as well as ice to get the water a bit colder. the water bottles will keep the ice frozen longer. You want the water cold enough to penetrate dressing.
