My cat ate almost 40 hair ties. We discovered this because she went into shock and required emergency surgery. The alternatives were an excruciating death or euthanasia. We were quoted up to $15k but got a relative steal at $7500. My partner fucking loves that cat.
I also have chronic pain and it’s really the worst. Sorry you’re saddled with it too. It’s interesting how if you say what you just did to “normal people”, they’ll often react by trying to talk you out of your opinion, but chronic pain sufferers usually just grunt their agreement.
