Hello, i am a 20 year old female. I noticed a slight pain when i sat on my tailbone a few days ago. I instantly checked for a pilodinal cyst or sinus but still i see no swelling or drainage or a hole. it is just like my buttcrack is sore. it burns when i touch it and hurts when i sit on it. i feel a burning sensation if i put a thing like a cream on it. what could it be ? im really scared of a pilodinal cyst.
