OP: There are many failed surgeries and remember once done, can't be reversed. I've lived with spine problems and I'm 83 and hear of those who have done a lot of surgeries and in a lot of misery.
Look at PRP therapy and I've posted a lot about it here. PRP providers are all over the U.S. and the world.
