Hi Sarah.
I hope your post-op appointment went well yesterday. I am 8 months post-op and have learned that this recovery is way long and slow. Also that surgeons offer vastly different advice for post-op weight bearing. I was no weight for 8 weeks, then partial for 4. As I've been recovering, I've had good days and bad...and have gone back into the boot a couple of times when it hurt too much to walk. (In fact, I was just in it this weekend, and am still limping around like I was back in March, so not sure what's going on!)
So, certainly follow your doctor's instructions, but I'd let your pain level be your guide. If your ankle hurts, ease back on what you're doing a bit, ice it, elevate it, keep using the crutches if you need to. Don't push it, so your body has a chance to heal.
That being said, given that mine still hurts, maybe you don't want to be taking advice from me! (Ha.) Everybody heals differently, has a different pain threshold, had slightly different procedures, and various doctors -- but the one thing that seems to be common is that recovery is long and slow. Good luck!
