I have a hard painful lump on the inside of the lower part of my left butt cheek. When I am sitting down then try to get up its painful. Any pressure I put on my left leg while walking hurts in that area. Even when I try to get up from laying down it seems as though I am putting too much pressure, and it hurts. It hurts when Im taking a shower and cleaning in that area, also it hurts when I try to wipe myself when Im done using the bathroom. It hurts with the slightest touch. What could this be, and what could the cause of this be from. Its so painful.
You are probably suffering from a gluteal abscess. Which usually starts as a superficial skin infection a gradually progresses and gets bigger and goes deeper. The condition can be extremely painful if not Chat Doctor.  First get your blood sugars tested, consult a surgeon, if there are no telltale signs of inflammation undergo a surface scan before going under the knife.
