text: tail bone pain... pilonidal cyst ??? pilonidal cyst ??? what is it? how do you get it? i said that i was having unbearable pain around my tailbone area... could this be what it possibly is?  there are no visable lumps, bumps, or "pimples" of any kind... i have not poped anything, as right now there is nothing to pop.  could it be under the skin? so that i can not see it? i always thought that i just had a tailbone that bruised easily until one time last spring when the pain started getting worse and it turned out that' i've always had a pilonidal cyst. i recccommend going to the doctor or the er if you don't have a doctor. if it's a cyst and hurts that much, there's a good chance it can't drain on it's own and you'll have to have it lanced. waiting will only make it worse.  the actual cyst is congential, but i think there are several different reasons it can become infected.
