sounds like you may have a problem with your sciatic nerve. this nerve is easily damaged. the pain with a damaged sciatic can be in either one side or both of you buttocks and sometimes more often than not the pain reradiates down the back of your leg. taking aleve or ibuprofen helps with the pain. i usually use a heating pad or a ice bag to help with the pain and take aleve and move around as much as possible. hope this helps.
i have sharp burning pain in my right buttock. i can't sit for long periods of time. i am also numb in my genital area as well.
