Can I have an abortion if I have a non life threatening condition?

In short, I have severe scoliosis which causes me pain in itself. But if I were to give birth, there would be a 50/50 chance I would be able to be given epidural and the risk of having my pain worsen making it so I would have to live in extreme pain for the rest of my life. In these circumstances, is it permissible for to abort?
