@bunnysammy This is short and easy. Doctors like to be lazy, especially when they think it will bring them more money. I have no sympathy for that. The first thing you need to do is to talk to a doctor who will order a whole genome sequencing for you. This will easily rule a big bunch of stuff which is not in your body. Or, to say it gently, regardless of what the doctor says, for a disease, if you ain't got the genes, you ain't got the disease. Find a geneticist who will help you through this search. You will need to have a genetics lab/geneticist who will work with Medicare and/or your insurance company, or pay the $500 yourself. If you have the freight to pay yourself, a good lab is Sequencing.com. There are many others. Dante Labs, etc. I would guess you have some sort of myeloma, maybe Crohn, Amyloidisis, etc. But until you get that WHOLE GENOME SEQUENCING, you are just wasting money. You can ask a reputable lab such as JohnHopkins, or Karmanos, or City of Hope. It would be nice if Medicare would make public a list of labs who have been approved by Medicare and insurances as providers.
