So anyway: the extremely sore arm came first. Was initially scared it might be carpal tunnel. Googling suggested otherwise. Was relieved to learn that it being on my right side was good news. (Left can be a sign of heart failure!) Doctor prescribed exercises and ointments and ice packs. Very weird, since I don't play tennis, but so be it.
Then, just as that was starting to heal, my stomach started hurting. A lot. After a couple days -- longer than heartburn's ever lasted before -- it got unbearable, so I got concerned. CAT Scan said acute appendicitis (which, hey, beats kidney stones or an ulcer), so I went to the emergency room and they took it out and I slept at the hospital for a night. And the thing about your appendix is, once it's gone, it's gone -- didn't need the thing in the first place! Tummy's fine now; arm's still sore, just not as much.
All of that happened in the past couple months, so naturally I constructed a playlist of music that helped me through. Most of the songs don't relate directly to said medical conditions, though at least two prominently feature pills (and one a hospital bed), and several concern trying to pay bills when there are more than enough of them to go around. But usually they're not too depressing about it. (Well, maybe once or twice.) There are two consecutive, highly boisterous songs about the economic difficulties of being an all-woman band on the road, which may well have nothing to do with the topic at hand, but you never know. There is also a song about assembly lines followed by a song about grocery lines followed by a song about unemployment lines which happened entirely by accident, I swear! Genres include vocal jazz, country, arena prog, funk, New Wave, didgeridoo soul-rock, gospel, Italo disco, and plenty of hard rock and metal, not necessarily in that order. Hey, whatever works, right? Can't vouch for you, but these worked for me.
