Thank you both, Bobbi and GJZH for your advice.

I am 20 at the moment but started at 17 with back pain, GJZH so you are right about thinking that I am young.

I will also ask about getting some tests. I have been told that they reckon my back pain is congenital. Degenerative Disc Disease sounds very similar in symptoms to mine so that could be what I've got.

I have heard that they can replace ligaments in the spine (Graf Ligamentoplasty, etc) so I might ask them about that and see what they say as this sounds like the most appropriate treatment.
