Chronic pain, a particularly pointed insight from Twitter.

Apparently it's Pain Awareness Month which is weird to me because I have chronic pain and I'm literally always aware of it. Seriously. Yes, it's exhausting thanks for asking, and if you mention kombucha or trying yoga I will maybe scream.

And later in her thread:

Honestly though, there is no one size fits all solution to pain.

Also, you know how they say everyone breaks under torture eventually? Unmanaged 8-10 pain is like that. People get desperate and that's how the snake oil sellers get us.

I'll add that it doesn't have to be "8-10 pain", that is agonizing. Constant pain breaks people, even moderate or low level pain.
And even if you're "dealing with it", it's an ongoing distraction and interference with life.
