<s>[INST] I fell several days ago onto my bum. A couple days ago while sitting my tailbone popped. Now it is extremely painful to sit down directly on my bum and I cannot bend over without a great amount of pressure. When laying down in bed I have to lay on my side as the pain from laying on my back is awful as well. Is there anything that I can do to alleviate the pain? [/INST] hello....according to me two conditions can lead to pain in your tail bone...first is a coccyx fracture and second one is coccygodyenia....you should get a xray done of your tail bone get precise dignosis....however till the time avoid sitting on hard chairs...also you can use ring pillows to sit on...take painkillers for 7 to 10 days ...apply ice over the tailbone....feel free to discuss your xray findings...thanks and dont worry... </s>
