TOPIC: I am planning on fat injection surgery for girth

I am only doing this bc my doctor recommended it to me. However what is any of you expreriences with fat injection as opposed to the other type of Girth enhancement.

Also after fat injection woul dI be able to get an Ellanse or HA later on if i wanted to. Or would it cause problem bc it would mix together the injections and maybe cuase a reaction? THANKS
