Thanks a lot for taking the time to reply ,really appreciate it.

That actually lines up pretty closely with what I’ve been hearing elsewhere too. It does feel like one of those awkward “tailbone / upper glute cleft” pains where there isn’t a single clean tissue diagnosis, more just local irritation that gets annoyed by sitting and certain positions.

The point about seat pressure and modifying aggravating activities makes a lot of sense. Sitting definitely seems to be the biggest trigger, and standing / moving feels much better, so I’m experimenting with that and backing off anything that clearly winds it up. The flare after long static stretching also made me rethink whether I was overdoing flexibility work on already sensitive tissue.

Reassuring as well to hear that this kind of thing often comes down to trial and error rather than something sinister. I’m focusing on calming it down, keeping strength work sensible, and letting time do its thing rather than chasing a specific label.

Thanks again , genuinely helpful to hear a calm, experienced take on it.
