My heartfelt thanks to all of you!
Dad is back home, swelling is greatly reduced, pain has subsided to the point where Tylenol will handle it. What was it?? Nobody knows. Ask four doctors, and get four different answers. Bloodwork points to infection, but one doc says 'gout' and another says 'arthritis', but nobody comes up with an answer that is backed up by the lab work. How sad is that??
As for me, I've been up to my usual routine, but still not 100%, although today was pretty good, especially after the two and a half hour nap I got while waiting for another truck to show up on the job site!
