u pulled a muscle yeah its very painful... i never had it on my butt before tho but knew someone that did same thing?

Do you sit a lot during the day? I've had a few friends that that has happened to. If so, what is the surface of your seat made of? Is it comfortable? How old is it?

[paints]

I think Falconer is on the right track.

I sit a lot at my computer, and I've had a couple of times when after a long day, I've got up the next morning with my butt stiff and hurting.

I put a cushion in my computer chair, and get up and walk around and do stretching exercises to loosen up the muscles in my legs and backside.

It also helps to do butt scrunches while you're sitting. 

Hope this helps.

well yes i was sitting in computer chair for about 4 hours stuffing envelopes but ive done that before and never hurt

could've pulled a muscle in your sleep tossing and turning, or maybe just cramping? try eating a couple of bananas for potassium, might help

this sounds like it could be a medical problem you, should go check it out even if it goes away, when things happen like that the body is trying to tell you some thing, so be smart and take time out to go check it out.  don't be sorry later.

See if you can find someone who will kiss it and make it well, that always worked when I was a kid.

I have no idea but thanks for the laugh.

You may have been sitting a little differently then you normaly do. I have to get up and move around a lot when i am at the computer.

I know the feeling.  I have been plagued with aches and pains from sitting at the computer too long.  I bought an extra thick pillow to take care of that.

actually rearranged the way i sit to work has worked wonders and even ate some bannannas dont know which helped but i am feeling better thank you
