I am so sorry. You must be so worried but you are never alone.
Sadly, some of us are having extra rotten luck right now. I wish you had not had to join us.
So are they putting you in a boot? I guess they want your MRI first. Maybe they could put you on Fosamax to help bone density if you don't take it already. I know that bone issues and fractures can arise from CRPS just ask sweet Enna. She can tell you.
I hope you end up with the least onerous possiblity and mend soon!
