Tia ,I'm sorry your going through this ,is a lot to handle and yes ,crsp and surgery is subject that we all got scare of for sure.
I had a surgery to treat my rsd/crps which gave me the worse pain I had and still have ,I battled a dr decision to let an scs implanted in my good leg and ended with rsd spreading and nerve damage ,so yes remove it the best option and take good care after the surgery with the right pain meds will give you relief of not feeling In danger of spreading ,trust me even one tablet a day will give you that sense of security .
I hope you get better soon and let us know how it went . Jesika .
Ps always go prepare with questions and do your research,learn the most you can and keep a journal handy with dr appointments add comments of what you discussed , meds ,ect ,it is the best inversion you can make , many times you will be the one teaching your dr about your own condition be always prepare , some links to help,
