@dixb Many people I know have CRPS and using LDL for their pain and as you said insurance doesn't pay for it but if it relieves the pain it's worth the money. I CANNOT use it because I am on a Fentanyl patch. My doctor did prescribe a clean w/ Lidocane and Voltaren in a paste at a compound pharmacy and works great for my osteoarthritis! Not so much for CRPS!! I use THC RSO Gummies made by Encore and extremely happy. The RSO is the part usually stripped away but now found pain relief !! I use 1 for daytime and another flavor for night. I sleep much better now. I have had CRPS for 21 years and will NEVER give up!! Blessings you! Gentle hugs
