I Have Had Problemd With My Back Since I Was

I have had problemd with my back since I was 13, I am now 27. I was told in one of those school screenings that I should go get further testing becsuse at the end of my spine there is a pretty noticeable curve. Well I was getting out of the shower yesterday and I have never been so scared, I almost dropped to the floor and felt parslised. What could the problem be? Can it be serious?
