I have a chronic condition that causes pain. One of the things I've learned, in as much as I can, is I don't tell anyone. I'd rather be rude than explain I'm in pain. Not because I don't appreciate sympathy. Not because I'm ashamed. It's because I don't want your advice on how to make the pain go away or to deal with it. I'm tired of advice. I've got too much advice. I try things, I research issues. I talk to doctors…
Edit to add: asking a question, if they're willing to answer - they don't have to, in case someone might know of a treatment or research they're not aware of yet, warrants being asked - unless we as a society want to be weak, shy, disengaged, and isolated in our suffering.
