@dlowan,
Fairly severe pain for the last few weeks? How come we didn't know that?
Or did you say, and I missed it? I knew about the head-bashing but I thought it was pretty much under control.
Very sorry about the severe pain!! Yes, it's exhausting, and that's happened to me too when the pain is finally relieved. (Conk out.) Very, very glad that you've found some significant pain relief.
