I'm an 18 year old male basketball player. I started having pain in may of 2013 in my lower back and numbness in my toes and feet when playing basketball. I had an xray and it didnt show anything abnormal. The pain has come and gone a few times since. Ok well in the past month and a half the pain has been here the whole times. I have lower back pain when standing.it hurt my tailbone my lower back when I sit.when I lay on my back it hurts. when I sit for long periods of time I get pain down my leg and burning sensation. my mom have two herniated disc so it runs in the family. usually when I have pain goes away but this time it has stayed the whole time.
what would be causing lower back pain and tailbone pain?
I appreciate any help and I'm sorry for the grammar I am talking into my tablet while in pain.
