Doc ran battery of tests, and localized the pain source to my elbow. I was a little skeptical, but I must admit that it was the only place that actively hurt while we wrung out my whole armal region, from shoulder to wrist. And it hurt rather a lot.
He pronounced it as lateral something-or-other (feel dumb for not writing it down now),
took X-rays to be sure I wasn't hosting any bone-gnawing alien symbiotes (negative), and prescribed anti-inflammatory pills, ice, and taking it easy until next week. I will do this.
He had nothing to say about my "sunburned" feeling except to keep an eye out for shingles. OK.
I am also self-medicating with a wrist brace from CVS. Yes, I know not to treat it as a cure-all, but it seems a not wholly unwise adjustment, just the same.
Blessings again to all who virtually frog-marched me into the doctor's office yesterday. I wasn't expecting to hear that, and therefore needed to hear that.
