Ouch! I'm so sorry to hear about your fall and nose, Mary!!

I really hope that you start feeling better soon and that the fracture heals OK and you don't develop any further problems!!
I always worry about falling and injuring myself also. My RSD leg is pretty unstable so I lose my balance quite often and have fell a few times and had RSD spreads and flares. When I fell about 2 months ago, my leg gave way and I ended up with a major RSD flare where the doctor thought I had fractured my arm until I had it re-xrayed! It's so scary what this condition can do to you!!
Please take it easy and follow your doctors instructions!!
I'm keeping you in my thoughts and prayers and sending many pain-free hugs your way!! Feel better soon!
