I've been through this before.
I know what's happening. The doc said get a cat scan, I haven't done it.
I figure about the time it gets to the "extremely painful" part, I will head to a hospital and the rest of it I will get over with.
The pain started in my kidney area. It moved - ever so slowly - down. It's been in my side for a week.
Suddenly? It's moved perilously close to the "exit stage", is what I am calling it. I mean, this thing moved quite a bit - all of a sudden - maybe 5 minutes ago.
If I miss a day's worth of entries, you might be able to guess with this information what is going on. Umm, hopefully, it's not more than a day!
