Feels like I'm sitting on something

Some people actually have a vestigial tail bone that protrudes a bit farter than is comfortable. You can actually have a surgery to shave it down, so you might want to talk to your doctor about it.  I do hear that the surgery recovery is quite painful, but it might give you long-term relief.  Just a thought!

Yea It's the tailbone, I've been there, it gets better.  sometimes when it hurts I kinda have to wiggle my butt around to move the loose skin, so embarrassing.  Good luck and hope you feel better soon.

I have the same problem.  It's your tailbone most likely.  Mine is really noticeable when laying on my back I feel it.  Hard to get comfy!

As I write these words I am sitting on an oval shaped foam cushion because my tail bone has become an issue whenever I sit.  (Google ****yx cushion) They sell them at pharmacies,

I have been in terrible pain everytime I sit for about 9 months now. At first I thought there was a lump in my car seat - it is an old car and thought it got lumpy LOL!!  Then I started noticing the pain everywhere I sit and I felt back there and I can actually feel the bone sticking out.  It isn't fun.  I bought a special pillow called a ****yx pillow - do an internet search and you will find it.  It has a cutout in the back for the tailbone and it is a lifesaver.  Hope this helps.  I do hope it goes away but so far, nothing

I think you are experiencing loose skin that is folding over.  I have the same feeling and it is not my tailbone- hopefully when I get my lift my plastic surgeon said that would be gone.  Check with a plastics person.

 i am 4 yrs out.. and my arse still goes through bouts of aching and burning from sitting.. 

i sit on a pillow, and a ring pillow....  some days are better then others,... it doesnt hurt until i sit for long periods..... so on days i keep busy  no problem... winter is worse as i stay in from the cold..

Did you ever find out what this feeling is......... doctors cant find anything

 Thanks everyone for the responses!  I was afraid I had some undiagnosed tumor or something.  It is such a strange sensation.  I started feeling it in the car each day and then noticed I would feel it sitting on the bed.  Before long, it didn't matter where I was sitting!  Luckily, I am not in pain it is just a very foreign feeling.  Good luck to all of you who are having to use the ring pillows.  I may be there soon.     Mary
