So many ways for Doc's to take advantage of the elderly. My first kidney stone Dr. took out the stone, and he wanted to sell me his "special" drugs...he owned the company that produced them. I said I don't want more untested drugs. My family Dr. that was into more natural things, told me not to take untested drugs. When I had another stone, and gave my Dr. the symptoms, he did tests and they came out all wrong, he sent me to the endocrinologist. She knew where to look...begin tumor on the parathyroid. Had it taken out, and all is well. I've told this story before, but if someone happens upon this....if your specialist wants to sell you their drugs....run the other way. When the surgeon called the kidney Dr. and told him what I had....he wasn't happy! In other words, he got caught!
