I would have a frank discussion with the nursing school
administrator or dean as to your limitations. Is this a condition that is likely to get worse as you age?
As to using a wheelchair - probably not while doing clinicals but if you choose a job where you are not in direct pt contact, or with limited pt contact, I would think that jobs would be available.
I admit that I had not heard of this before so looked it up: What helps?
There are several nonpharmacotherapeutics too listed. This website also lists lifting as being counterproductive and possibly may increase symptoms.
As a nurse, you will be expected to lift patients.
I'm going back to my original suggestion - bring in some written info for the dean/admin to discuss with them or go directly to the ADA office of the school/campus you wish to attend and see what they say.
