The orthopedist I saw in Md. for my knees initially told me I had avascular necrosis, which means the joint is being starved of blood, and the bones will die. Another time he said that I was going to have to get a knee replacement because of arthritis symptoms because there was nothing he could do. Then when I got back from the Mayo Clinic in Jacksonville, FL, he asked me why I went down there, like he was insulted or something, and I told him to his face that he gave me two diagnoses that were not only the worst possible, but negligent. Turns out I had a baker's cyst behind my knee that could be treated with an occasional cortisone shot, and there was no structural damage in it, and as long as I took a diuretic from time to time, the swelling my neuropathy generated could be controlled. What a jerk.
