You might want to start with the FDA. I forget what i've read so far about your symptoms but are you having trouble with getting a diagnosis? If you have symptoms are you on meds yet? if so are they helping? We could have pd from some of what we've allowed to be shot into our bodies. You asked what i'd do, i think i would avoid it for now. But FDA can tell you if there are previous complaints. These people at Columbia continued for years after failing FDA inspection. Maybe you don't have to have a PET scan.

that's the problem. in good conscience, who can recommend a pet scan to anyone right now?

good luck and keep us posted please.
