puma is a little pill and what you do is at least in my sons case he would take this pill about hour before the test and you are suppose to eat something greasy so it gets absorded in the system.then you go to the drs off. and they put you in like a tanning booth. in the beginning you stay in for just acouple min.the only bad thing about this treatment it breaks dowm the immune system so its easier to pick up colds and other things they also check for skin cancer.if you want more details you can email me. This disease is very hard on the person who has it and their family.
