OK, so tests came back and everything’s fine.
Everyone’s happy with the results. No need for further tests. And my dietary numbers look good, too. Well, not good, but better.
I’m still not allowed to exercise. Exercise may have contributed to the situation, actually. (Though my money’s still on the antibiotics.)
In any event, I’m good to go. I live…again.
UPDATE: And pardon my manners. Thank you all for being so supportive here. Means a lot, even though I wasn’t all that communicative about it.
