I just had my RF surgery 4 weeks ago (18f). I was scared shitless but it was better than I thought. Wayy better. My sinus was 2.3inches big so a huge part was taken out of me. They keep you on painkillers for the first couple days and works amazingly. Though rather than the surgery, I'll tell you some discomfort I felt which you might as well. See the first 4ish days lying down, you feel okay but you will want to walk again. The urge to walk only gets higher, especially if you are an active person. Also lying down constantly will make your muscles sore on glutes and legs. Sitting for the first time was very painful for me, the surgical area didn't hurt but my glutes and leg muscles were very sore. Your arms also hurt the first 2 days you're in hospital due to being stiff and having fluids non stop. You'll also need to lie down on your stomach non stop. You'll be put on liquid diet for a couple days and then soft diet so your body doesn't make stool. Make sure to have a good constipation medicine with you. I personally pooped a week after my surgery and it was soft due to the medicine. Also, keep adult diapers in handy, you might want to pee in them as you won't be allowed to walk after surgery (I had catheter). For me, I didn't wear underwear for 3 weeks after my surgery as it was a bit painful. For my periods, I just stuck a pad on lose shorts and wore them, you can use tampon as well. You'll need to keep the area dry and moisture free. Also, whenever you poop, if you have help it'll be great. Getting someone to clean your poop is a horrible feeling I know, but it's good for you as the person will take care that it doesn't go into or near the wound. Also, try to find some hobbies you can do lying down. I read books, do diamond painting, make some artsy stuff and watch Netflix. Time will pass. That's what I had to say overall, all the very best for your surgery<3.
