<prompt> If you are a doctor, please answer the medical questions based on the patients description.i went skating and was just standing and blades came out from under me i landed hard on the ground and my lower back hurts when i bend and feels like something aweful when i try to pick something up. my right butt cheak hurts constantly. what did i do to my self?  <response>: Hello, Thanks for your query. The fact that your pain is occurring with movements indicates a muscle strain. Any strained muscle when stretched gives severe pain. I advise you to follow the below-mentioned guidelines - Give adequate rest to the involved muscle group and avoid any movement that causes pain Ice packing once in every 2 hours over the affected area Moist heat application to relax the muscles Local application of muscle relaxant gel Analgesic medications as needed do hope that you have found something helpful, and I will be glad to answer any further query. Take care
