Can you provide lower back sclerotherapy injections?

I had an unsuccessful decompressive laminectomy on my L 4&5 discs in 1988. Afterwards my osteopath in Spokane Wa. used sclerotherapy injections in my lower back and removed all pain! He told me if I saw him 1st surgery could have been avoided. I needed a booster in 2000 and got one from a doc in Jefferson City, Mo. I badly need another booster. I'm 59, am 5'11 @200lbs. am retired in OKC. OK. The injections never cost to much. Is this technique still available?
