Tammy I dont know if you have the funds but there is an EXCELLENT LS dr in Tenn. Shes the best and probably the one with best prices. I would suggest you join

They can help you with all those questions you have and they will suggest the same dr. I know of someone who traveled all the way from NY to see her. If you cannot get there Im sure their are drs who do the surgery in your area.
Here is Dr Tobia's website
