Painful to sit for long

[1AngelicFruitCake]

I went to an old fashioned cinema about a month ago and the seats were really uncomfortable and the base of my bottom was sore from sitting on the seat the next day. Since then if I have to sit for long I have to brace myself as i stand up as I know it’ll be painful. I now can’t sit fr too long on a firm chair without getting achey. Any ideas?

Long shot but it could be an abscess or cyst. Is common with the symptoms you’re describing

If you've buised your coccyx it can be painful for ages.

Thanks all. I appreciate the replies. I don’t think it’s a cyst, bruised coccyx sounds possible, it’s never happened to me before so have had no idea what I’ve done!
I definitely need to try stretching/strengthening and just be fitter in general!
