I am having this procedure done in a month. I am told I will be having 20 injections at one time. I see in your statement about how people did after having it done received 1 or 2 shots. Why would I be told 20 shots ? And if it only last 6 to 8 months, how often does insurance deny paying for it? I was quoted the procedure costs $23,000.00. I will have to pay $600.00. Sounds like I may get 6 to 8 months of relief. Sad.
