For my RTS I didn’t realize I was suppose to take them routinely but for my TKR I WAS ON 6 weeks of anti inflammatories alternating with Tylenol and 6 weeks aspirin Do you have an ice machine. Yes if u have colitis that does make things a little more difficult but I found narcotics didn’t do much of anything and very constipating, I still have leftovers from both surgeries. I purchased a bolster prior to surgery that my therapist recommended that helped with the swelling. I forget how many weeks out but using a rolling pin daily for 3 minutes down each side. He always does deep tissue massage and has always worked the knee cap and now he has taught me how to do that too. Utilize your therapist if they are really good they can help tremendously but not doing therapy will most likely make pain worse and probably allow scar tissue to form. I did pt prior to TKR. On my first day home was in therapist office and I was 0 degrees and was on the recumbent bike and got to 62 degrees. Hang in there it’s not a sprint but a marathon! Also eat anti inflammatory diet if you can. My pain was around for three months, I felt so sleep deprived. Went well after that for a while, pain again for short period which I was told was normal. Still working hard on endurance and continue with my stretching, exercise bike and other exercises therapist has me do. I’m still working on the marathon for both my shoulder replacement and my knee. Gotta keep up my exercises.
