Hi Foggymama- I just finally got caught up on this thread. Wow, you have had an incredible journey, and look how far you have come!
I also have the issue of thinking every new/different pain is some failure coming on. Of course this is more prevalent when it happens in the middle of the night, when I can obsess about it with no distractions

It really helped for me to ask a bunch of those nagging questions at my followup appt today. I had decided to just start writing down my concerns on a big list when I started obsessing (which really got more intense day before yesterday, so I knew I had an appointment soon). It helped to dump it out of my mind and onto paper, and then I had a list of questions ready for the appointment. They also said not to hesitate to call when these come up, which I was going to do one day, but by the time daytime had come around the pain had resolved. Anyway, don't be hesitant to call your doc's office if you have questions about whether pain is normal.
One of mine is sharp butt pain (which confused me due to its intensity and the fact I had the anterior approach). That night in the middle of the night I was convinced that I had broken my hip (I tend to go straight to the worst outcome at that time of day). Then my rational brain turned on and reminded me that I have broken bones before and this felt nothing like that shooting broken bone pain. Plus it was starting to feel better with ice. Such drama! (all in my head of course ;) Turns out it is most likely an unhappy muscle (a) my hip is now oriented a bit differently due to the new joint, so the muscles are complaining a bit, and (b) sometimes they cramp just from the insult of surgery and then not moving much. Makes sense, since ice seems to alleviate the issue.
Anyway, so glad you are progressing so well. Too bad we aren't a little closer on the I-5 corridor, or we could go on (short) walks together.
