We're in the practice of speaking English on this board, not IM'ish. Please take a little time and at least ATTEMPT to spell correctly instead of using time saving shortcuts that are meaningless when people read the message 24hours after you type it. After a while, you might find that such skills may help you in career endeavours.
Now regarding your talibone. Most people get lower back pain from bumpy cycling, not a tailbone pain. I'm going to guess that you fell one day and landed on it. If your seat is pointed too far forwards, it may actually be rubbing against your tailbone and aggravating it.
Try moving the nose of your saddle up. You might also try a suspension seatpost (on a hardtail) to minimize the amount of shock your backside is getting. If it doesn't get any better, take it to the doctor.
