Hi, I don't know this Cooled RF work but know about PRP (platlet rich plasma) injections, Stem Cells injections and Prolozone injections (oxygen/ozone) ... these are all out of pocket injections and are pricey and no guarantees to any of them. I'm thinking and thinking on the Prolozone as it's the least pricey.

You can find info online all all the above mentioned. It's my knee that I would start with...funds are my issue. Surgery is my very very least action I'd take.
