Hey im a 13 yr old girl that was playing basketball 2 months ago when i got 2 brusises in my lower spine. i didnt hit it or antything when i came back from playing basketball for 2 hrs it just started hurting just in that spot when i lay down on my piliow. Its been there for about 2 months and i just want to know id i should be worried. The top brusie did get a little bigger but since they stayed the same, is there anything i should do
