I'm happy to report that I seem to be improving slightly. Yesterday afternoon, I drove to the post office to pick up my mail (3 miles) without as much pain as even earlier in the day. Today I'm going to try grocery shopping (16 miles, round trip)--what a thrill! (I mean that literally!)
For any of you who haven't had a Shingles vaccine, I strongly recommend that you get one ASAP. You don't want this, and I don't want it again. As soon as I'm over it, I plan to get vaccinated before it has a chance to return.
Thanks for all your comments and prayers--I cherish them all.
