Well in all honesty my advice would be to NOT apply for the job, I think your health and well being is your top priority, and I think you seem the sort of person who would only like to give 100 per cent in your job, so in all honesty do you think you will beable.

You should take the time you need to heal properly and not put yourself through anything un-necessary, then you will be in tip-top condition hopefully and beable to take on any task or job you wish.

I know it can be no fun being on disability, but personally I think waiting would be a wise decision, that is just my two cents worth, but the job just sounds too much sitting for someone undergoing recovery from back surgery.
