Can A Tiny Lipoma On Spine What Can This Be? (urgent Please Help Me! Thanks!)?

What can this be? (urgent please help me! thanks!)? - can a tiny lipoma on spine

So, for 1 ½ years ago I had a dime, very flat, very noticeable, painless, a little soft (if I press really hard ... but not hard rock) "thing" in my end crack about an inch below the top of my butt crack, and slightly to the left of the spine. were observed during the season, and when I am very sick, but then once it reaches the size it is now time to suffer. has not increased since I've noticed, but lately (last month ISH) I played a lot, so it is perhaps a little bigger, but not significantly. the fact that the ground is what makes me confused and without pain, and my first thought on this "mass" (which btw is not visible from the outside at all in some way, no, do, or redness orut-ness). Sometimes the night is a little itchy, but only recently, so I think it's probably because I still play. I'm not at all for the first year that I will affect what can that be? oh, and it was different, but much deeper, much smaller and an inch and it is still very small, about the size of a pea (). What could this strange sorta soft real estate is that possible? I sit on the coccyx is often, and I am 16 years old and a girl, and I'm average weight (a little) on the weak side - I read that could be a lipoma () a little bit fat, a but the May, If I 'm certainly not fat? lol. well please help me! Essentially, what hope there is no factualr aaah well please help! Thank you!
