<s>[INST] I slipped on some wet cement tiles today and landed on my left butt cheek, not my tailbone, and now I am in a lot of pain. I know you can t break your butt cheek, but what would cause so much pain. It is not bruised, it just hurts a lot. It is hard for me to walk and I can t sit on that side of my butt. My question is what could be causing so much pain? [/INST] Hi, Thank you for providing the brief history of you. As you mentioned the mechanism of injury we should understand that when ever there is a fall, there might be two things, either muscular injury or either a bony injury. Undergoing an MRI of the Lumbar spine will help provide some input. Sometimes due to fall there are chances that you may damage the soft tissue of the lumbar spine and also the bony alignments are disturbed. The reason for this is the whole load is borne by the lumbar spine as there is a tremendous thrust on the hip region due to fall. Most cases landing on the hip region during the fall, land into the injury of the lumbar spine and get misdiagnosed due to improper assessment plan. I will recommend undergoing an MRI of the lumbar spine to get assess further into the depth of the issue. RegardsJay In Chat Doctor.  </s>
