I hope it lasts too, but I think by now we all know many have to go back for 2 or 3 times.
I found a Dr who will do it and has spots open, but he is on the other side of the US and to be honest I'm scared now. I've read where a few got worse a couple of months after and others it did not help.
I'm open to almost anything, but the possibility of getting worse scares the heck out of me. So, I'm waiting to see how this works out.
