Thank you, Hensylee, Les, and Birky.
I didn't realize there might still be tender spots after so long a time in a normal postop. Hopefully not at the level of pain yaps was referring to. Is it the nasty ends of those #5 wires, as Birky seems to suggest?
I guess each surgeon wires them a different way, or may relegate that task to a surgical intern. I have eight #5s, but they don't seem to bother me, so I'll just count myself lucky again.
Yaps, there still shouldn't be anything rubbing against anything else inside your chest, especially if it's enough to produce a grinding noise. I suppose it could be just a loosened wire, rubbing on its moorings, but that doesn't sound too good, either. You're sure it isn't just a snoring canine that's producing those harmonics?
Best wishes,
