Tailbone pain??

yes get a cushion! i had previous surgery near my tailbone so i already had pain when sitting...now it's worse. i have to constantly adjust the way i'm sitting, shifting weight from one side to the other to relieve the pressure from my tailbone. if i'm sitting in a hard seat i have to use my donut cushion. i actually noticed yesterday after sitting and my tailbone hurting that it was super red around the tailbone area. i've read on here that some of the pain is b/c we have lost the extra padding and also there is a muscle that like pulls the tailbone up when you sit down...since we had extra padding that muscle didn't have to work as hard so now that we don't have the extra padding that muscle is still weak and doesn't pull or adjust the tailbone like we need it. i hope i have that right! lol.
