My Mama has suffered with Psoriasis her whole life and, like you, has tried everything. A few years ago, a doctor gave her a Rumacade (I am spelling it how I pronounce it, so the spelling is probably wrong.) infusion treatment and her Psoriasis went away.
She moved to my state over a year ago and has been trying to get this treatment, but her white blood count was low and the doctor didn't want to do it. Well, long story short, we finally convinced the doctor to give this treatment Monday. I dropped her off at 9 and picked her up a little after twelve. She felt fine...not tired or anything. Tuesday, her psorasis was completely gone! I have never been so shocked in my life. Usually it takes a week for her skin to clear up...but this was a matter of hours and the psorasis completely covered her body. So, I am totally sold on this....She is like a new person...so happy....wants to go out now and not stay inside....smiling...It's like I have a new Mama.
