I am going to do the Echolight Scan that so many people have talked about, as it seems that it gathers more information on the bone and the integrity of the bone. I dont know if my insurance will cover this, but for me it is $240.00. I am then going to get with my doctor regarding this, and ask alot of questions. Ask what every option available is. I tend to be medication resistant so, my options seem limited. Ask questions, do research, talk with your doctor, pick peoples brains on here, and then make a decision, that is best for you.
