pre nursing student concerned

I am a pre nursing student, currently (at least, that's what the school calls me - I can apply for the program itself this winter). I worked for two months in a Nursing Residence in dietary before I took a fall there. I have a herniated disk and severe bursitis in both hips. I can't stand for more than a couple hours without intense pain, currently, and often am scared to work at all. I go to PT and see specialists consistently, and the next step is cortisone. I am considering a less physical job while I'm pursuing my nursing degree in hopes that this will help with healing - along with an active lifestyle outside of work.

I have this small fear that this is going to affect my career choice, but I'm refusing to give up. If anyone has been in this position though, I would love some input. I've always been active, never had problems like this until my fall - and they're probably dropping my comp soon -

Does this seem like a good thing? I mean, this would give me years to work with this and manage the pain so it seems smart to me, and because I can barely work in my current job, my priorities are shifting to the financial burdens of now.

Also, has anyone had cortisone shots? My doctor has assured me there are no long term effects but I've read and heard many different things.

I don't know, I guess the past few months have made me a little skittish, I guess I just keep pushing through and try to get stronger. I hate missing work because I love the residents there but I guess I'm just paranoid that this is never gunna go away.

Thanks.
