Thank you, everyone, who posted in response to my "Worrying" about
carbon monoxide. I had the test last night, and it came out negative.
I also bought a CO monitor, and so far, it hasn't picked up anything
in my apartment. So that's one less thing to worry about. Kitties are
safe (at least from that).

However, I'm still very tired. I got some other lab results back, and
both thyroid and blood count looked normal. So I still don't know
*why* I'm so tired. I have been working very hard over the past few
months, had a number of very long days, and in general have worked at
a fast pace. So I don't know, maybe that's catching up with me.

I also started to develop a new problem yesterday: lower back pain,
possibly on the sciatic nerve. I've had chronic back trouble for years,
but usually only in specific circumstances, such as when I'm standing
in one place for too long, or I've been walking for more than about
a half hour, then I need to stop and do stretches. But yesterday, I got
a new pain that I haven't felt before. It's a deep ache, and starts in
the lower back and spreads down the backs of *both* legs. The worst
thing about it is that I can't get comfortable when it's bothering me.
Mostly I've been able to sit in a chair without back pain, but not
with this. It hurts no matter what I'm doing, and last night it really
disturbed my sleep, because I couldn't get comfortable no matter what
position I was in.

The only thing that helps is ibuprofen, so I've been taking that regularly.
So now I'm going to have to go back to the HMO and try to get Xrays or
an MRI. Something's up. And I don't think this caused my tiredness because
the back pain started yesterday, and I've been feeling exhausted since
Saturday.

Ugh! Getting old sucks! Thanks for listening.
