Hello, when I was 13 my lower back started to hurt and I could feel something there. My parents took me to get an xray and we found out I have an extra bone there on my spine. My back hurts every night. When my bladder is full and I am laying down that's when my back hurts the most. Is there anything I can do about that? I am worried if I get pregnant my baby will push on my bladder and my bladder will push on my spine and I will be in pain 24/7. My back sometimes hurts even when I am gassy. What doctor should I go to to get this checked? Thank you, Karolina.
