Answers: your butt? or your coxix bone?
could be misalighnment of the tailbone because it happens to me as well, or it could be your siatika you need to get a back friendly chair
maybe to much weight put on it, try walking for a minute or so if that happens
well they say you should get up and move around every 15-30 minutes to avoid problems like this. also, look away from the screen every 15 minutes to avoid eye strain.
