Glad to hear your AN surgery is scheduled; sorry to hear about the hip replacement.
I've had AN surgery (retrosigmoid) and the recovery wasn't as horrendous as I thought it might be. A lot depends on the side-effects you encounter post op.
Don't get me wrong, it was major surgery and at times recovery was very challenging, but all in all I have to say that the first days were definitely the worst. My doc said it would take about 6 weeks for recovery, and while the fatigue lasted way beyond that, most of the "big" issues (like balance) were cleared up before then. Not that everything was perfect within 6 weeks, but I was definitely functional and well into getting back into my normal routine (back to work, back to driving, etc). I know that recovery is different for everyone - this is just my experience.
As for the hip replacement, I haven't done that yet. But a few of my family members have - hip problems run in my family as we age. My grandmother had both her hips replace when she was in her 90's and my dad (who will be 81 next month) has had 3 hip replacements. Yes, I know, he only has 2 hips - but one was replaced about 15 years ago and last year it had to be replaced again.
Recovery from hip surgery - at least in my dad's case - takes some time but with physical therapy things move fairly quickly. The docs are also very quick to get patients back up on their feet (with a walker) a day or two post op.
60 is certainly not old and being in good health should only help you. Obviously your docs will have the final decision, but I don't think you'll have a problem having the hip replacement in January.
Please keep us posted,
Jan
