@artdcsping, wish I new about plasma replacement therapy some ten years ago as I ended up having hip replacements so now I'm in the spinal stenosis stage where my spine is closing and my legs are giving out from underneath me. I'm only 69 and I have a lot of life left but as the spinal problems increase I'm unable to bend over or even do the minimum in keeping up a house so I'd like to read up about this replacement therapyunless it's too late for me .plasma therapy wonder if that would work for the degenerated discs in my lower back?
