I am 26 and currently being treated for L5/S1 disc prolapse plus the four above protruding. I understand that you feel your job may put pressure on your back.
However,
My back was actually damaged from an office job I did when I was 16!
I am a manager of a care home for older people, and I have worked in care for the last seven years. As somebody with back trouble, I feel very strongly about lifting and my staff never lift. I have actually formally disciplined staff who I have caught lifting! I'm sure if you explained to your employer about your situation they would also reassure you that, if you follow procedure, you will not risk further damage. If your employers are expecting you to lift then you have the right to refuse. I'm sure you're aware of the Manual Handling Operations Act and which maneouvres are illegal.

If you stay positive, you will find you feel a lot better
