Hey @cgent!, Thanks for the private message. I thought I would respond in the discussion I think you were trying to find -- Buttock/tailbone pain, sitting or lying down - symptom of PMR?: https://connect.mayoclinic.org/discussion/curious-about-this/.

Under the Sore butt 😂 indeed category, I'm with you which is why I love the reminder to stand once an hour on my Apple iWatch. Hope you don't mind but I will repeat your question so that others can chime in with their experience.

"Recently, although I've had no problems with PMR, my butt seems to be overly sensitive (not funny !!!) Whenever I drive the car or sit and watch TV for any length of time my butt really hurts ... the backs of my thighs and fanny hurt as if I've been sitting for many hours instead of a few minutes. I was just out mowing ... AGAIN ... and noticed that my type of mower, a small zero turn type ... bounces pretty wickedly when mowing at the faster speeds we tend to run these machines at. Again, my mower is smaller and lighter so it tends to bounce more. Could all this hard bouncing be bruising my fanny so that when I sit for a while it bothers me a lot ??? Do others who experience sore fanny's mow with small "bouncy" mowers ???"

Funny you mentioned zero turn mowers. I have a Ariens 42" zero turn and my yard is pretty rough to mow. Mostly I'm mowing 3/4 acre of prairie grass with lots of mole and gopher holes so the ride is pretty rough and hard on my postier if I go too fast. I mean who wants to take all day to mow the yard when there are other things to do. I have seriously thought about buying one of those special Purple seat cushions that I can move to wherever I sit - kind of spendy but if they help I would get one - https://purple.com/seat-cushions/portable. And my PMR is still in remission although I have been having a little more aches in the shoulders.

Anyone else have pain in the rear that may be associated with PMR, bouncy mowers or just plain sitting too long?
