Whenever you lose a significant amount of weight, it could alter your core balance and posture. Be sure that your lower back lumbar region is curved in, not slimped out,

My mom is way underweight, and can barely sit she is just bone on bone in her butt. No RA. I lost 30 lbs 2 years ago, and I could not travel in a car for more than a few hours, the pain was so bad.

I am trying to lose again, but doing lots of dance exercises. I really think you need to be able to jump and leap to build up those muscles, which is not within my ability.

Why does the fat pack on my belly, instead of my butt, is what I want to know!!

You can have various forms forms of arthritis in your spine.
I have Osteo in my neck and left side sacriliitis in my S!
i have another spot that hurts and I suspect I have anklyosing spondylitus(not confirmed), because of significan spine and nerve issuse that have started happening.

However, my S!, which i the last jointed vertabae, mostly cause pain a couple of inches above the end and in my hips. The end sometimes is a little sore, but not that bad and the nerses that branch off the tailbone go though the side,, not the bottom. This all being said, I would suspect that you just need to learn to sit differently or more gently until you can build up those muscles, but I think you sould ask your rheumatologist to make sure
And if sitting continues to be a problem you can get one of those cushions...don't remember what they are called, but they are so you can't put weight on your bone while sitting

Hope you can start to feel better soon, tailbone pain isn't much fun!

Re-read yoour post and if it is the hips you are refering too...could be caused by either RA or weight lose

So, ask Rheumy
and
Buy Cushion!
and
Stupid exercises!

I am suposed to join an exercise therapy group if my neurologist oks it Yuck!

Thanks very much for the replies. This is literally my rear. Not the joint, just the part that goes on the seat bottom. It sounds like what Angela mentioned - not comfortable on the bottom. I can switch around and it's fine - it's just that there is bone then flab...not hard muscle to cushion I guess. When I tighten those muscles they build up under the bone so I think I need to jump and leap. (lol Angela)

Aggie - yes! I slump all wrong. If I sit up straight I'm curving in. Thanks.

Add me to the list of bony buts. Before I spent the last 40 months on prednisone I had a bit of butt and wasn't very thick in the waist. Now the waist is thick and my Butt has pretty much disappeared making sitting without cushion an unpleasant issue also.

Just a quick comment, try not to walk behind me because of these physical changes occasionally my pants head for the ground. I have taken up wearing very nice and colorful undergarments just in case. The dang problem is by the time one recognizes the downward movement, the speed of deccent is increasing, the first response is to bend and grab, this further accelerates the rate of drop. DO NOT bend at the waist, reach quickly straight down and hope! Suspenders would be an answer if my shoulders could tolerate them but thanks to RA it will continue to be "WATCH OUT BELOW".
I blame this on prednisone especially the lack of butt padding.

@bcatz - my butt is usually well rounded, but I know what you're tking about. Do lunges and inclined walking (hills or treadmill) to get your butt back. Your sitz bones (really) are the bony protuberances, and there are some good muscles thatattach there.

@angela - try wearing your fat pack on your butt instead of your belly.

@inkjoy - good exercises. good exercises. good exercises.

@rayguy - pretty underwear won't help if the butt isn't there (butt do wear underwear, please). Have you tried elastic waist bands or even belts? Cute story.

@ roxie bad exercise, bad exercise, bad exercise


But luckily my mom is my exercise partner and betwwen the two of us we can usually keep going...once I get oked again.

i did lose weight. but alas (!) I feel like I "found" some of it back.....and my butt certainly DOES hurt when I sit. often,the tailbone but also what I think is a muscle on one cheek. (sorry not trying to be cheeky) lol.
that is all I can say. I sit on pillows as often as possible and get up a lot to move around.
