pain sitting down on hard surface like bench?
Oh YESSSSSS! I was confused quite some time, because I definitely can't sit on soft stuff, esp. sofas you sink into, cuz of my back/SI joint (SIJ).
So I always thought I liked harder seats. But squirmed around, couldn't sit anymore, changed position, put one foot under, had to get up.
In concerts, church and stuff I always sit where I can get up without disturbing anyone (or prefer services where people can get up for singing).
Then a doc-pain-questionnaire asked if I can sit for 30 or 60 mins. on a hard chair and that make me realise I can only sit there for max. 5 mins.
Now I know that, I am even more wary. In the talks about fibro & pain management in the rheum. clinic there were only hard chairs for all of us.
I used a jacket or top for sitting on for 3-4 mins. at a piece, the rest of the time I stood up or leant against a wall. And wondered how all the other fibro-patients managed. Only 1-2 others got up part of the time. But once they all complained at the end and the lecturing psychologist told us to put it in the feedback, so we all did. But I am still so surprised that they complained, but remained seated, even amongst ourselves...
In each PT-treatment, whether osteopathy, acupressure, exercises or local cold, I always get my SIJ treated, I wonder if it'll ever get better.
It also pains around at night, making sleeping esp. on my back "hard", even when cushioned. And even if that's not the reason I wake up, I often do back exercises or shower cold to get it back down. At daytime I control it better whilst lying on ma back. It can drive me so mad that I wish I could burn it out somehow. Or makes me want to run away from myself. That's the hard seats again. Avoiding those prevents the extreme.
