Does anyone feel his tailbone when sitting? Since I lost weight I can barely sit on any support. It's like I lost my cushions lol. when I sit on a flat surface I feel my thigh bone and joint, and my coccyx is uncomfortable and painful. At first, it was just a little sore sometimes, not having any real impact on my day-to-day. It slowly and gradually got more painful. Lately, if I'm on my feet, even just cooking or washing dishes, for only a half hour, my tailbone and the area around it throb and ache. I hope I'm not the only one around with this weird pain.
