Is this a manual wheelchair of which you speak? Or a motorized one?

I hope it's motorized; they've found that manual ones really tear up the rotator cuffs.

This has to be a real shock and upset for you. (((hugs)))) It has to feel unbelievable at times, and other times the reality must overwhelm you too.

I was in a wheelchair (long before motorized ones) for a short time during my twenties. Of course, I didn't know it wasn't permanent, and neither did the doctors. Now, for a different reason, I do use a motorized one for big activities, as I can't walk far without increasing my pain substantially.

Give yourself time to grasp this. There are great resources to help you find what you can do, and what new paths you wish to take now. Life goes on...it changes all the time, and can change again for you...even for the better.
