Medical Doctors, Not All, Just Some

I went to a local MD a couple of months ago, because my feet were numb and tingly. I explained my symptoms to her, and in her defense, she did exactly what I would have done in her place. I told her I didn't think I had a sugar problem, of which numb tingling feet, aka neuropathy, is an indication. However, on examination, she said she couldn't feel a pulse in my feet and was going to order an ultrasound on my feet and legs. Good call, since I HAVE had bypasses. She also drew blood to do lab work. Lab work came in fine, no diabetes, no anemia, no gout, good B-12. Everything FINE with my blood. Ultrasound said I had perfect circulation in my legs and feet. She said I probably had neuropathy and reccomended a neuropathist. Then she said since I was taking Niacin for vertigo and good cholesteral, that might be causing it and told me to lay off the Niacin for a while. I didn't much believe this, but it was an easy try.
Three weeks later, feet still tingling, so I made an appointment with a podiatrist. Gitting close to Dayton and I wanted some relief. Told him up front I didn't have sugar. He looked at my feet for a few minutes and decided to send me to a neuropothist (probably spelled wrong)
This WAS A TRIP. They wired me up, jolted me with electricity, stuck needles in my feet and immediately told me I HAD BLOOD SUGAR! Told him about doc number 1 He didn't care! I had sugar, no matter that he hadn't tested my blood or anything else medically!
The podiatrist called me 5 days later and told me I had blood sugar. Told him I did not have sugar, so he wanted to know if I wanted him to make me an appointment with some nerve doc that my insurance doesn't cover. I told him thanks anyway, that I thought I would see a chiropractor, which I did. He hasn't fixed my feet, but at least HE DID LISTEN when I told him my problems. He has gotten the feet feeling a little better, but the saga of the aching feets continues.
