RSD31 I'm so sorry to hear about the spread. Are they trying any meds. besides nerve block to help prevent this? I was told 500-1000 mg. of vitamin C can help so I do it in hopes.
I can only imagine how frustrating that is for you.
How did it spread ?
Let's pray for some relief for you and WE ALL NEED A CURE!

As far as more info. on nerve blocks I'm glad to share my experience for the others who may ask.

For a good visual there's a really good video on Youtube - just put in "Stellate Ganglion Block". I really like the one using ultrasound. Thankfully my Dr. uses both x-ray and ultrasound guidance.
