I agree that icing is crucial to reducing swelling, therefore pain. I was provided with an ice machine at the hospital, before discharge. I also was informed that freezing water bottles will work for cooling machine, as I do not have an ice maker. I believe it held 3 or 4 , 16oz bottles. I kept extra bottles in freezer to rotate. Your doctor should be able to write a script for it as well as for a walker, cane, etc. Hope your insurance will cover. I was fortunate that the hospital where I had surgery provided an information session prior to surgery. They showed us how to use all the adaptive equipment; sock adapter, reacher/grabber, how to adjust appropriate height for cane and walker. I was able to borrow an elevated chair with handrails for over toilet. Good luck!
