<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, recently i hurt my back, I was on a bouncy castle and had a fall and bent my back, head backwards towards heels. This caused a lot of discomfort to my back, momentarily winding me and later i noticed when i bent my torso down to the right my bottom rib at the back clicks out of position and then i have to bend the opposite way to click it back as while it is out of position it is quite painful, is this a cracked rib?  <response>: Hello. Thanks for writing to us. The bottom ribs out of position with pain are likely to be due to cracked ribs. However, diagnosis can only be confirmed after an X-ray. Take rest and take a mild painkiller till then for relief. Doing a hot fomentation will also help. I hope this information has been both informative and helpful for you.
