DDD

Hi

I have DDD L3 L4 L4 L5 2 discs pretty much wrecked,i am thinking of surgery or stem cells i have heard mixed reports on both.I have had animal stem cells ozone therapy and intravenous lazer but did not work. i am thinking of trying more stem cells human umbilical ones straight into disc or just get the M6 disc replacement operation. just wondering if anyone has had any of these treatments and did they work? Im 38 quite fit. work as a deep sea diver so also not sure if i can get disc replacement and work under pressure?? cheers for any info.
