Hello, I am glad you are doing your research. It is always important to gain knowledge about possible treatments before making a decision. I have not had cryotherapy or heard of it as a treatment for Fibro so I can't give you my personal account. I did find this article for you, you may have seen this in your research. I also wanted to just put a friendly reminder that it is always a good idea to ensure your doctor is well-informed of all treatment considerations / decisions. Hugs!
