Dr. comment bothersome?

I went to e.r. for what I thought was bad back pain, tests were run and sugar was 600. I had no idea I was diabetic. Other tests were run and my hemoglobin test was 15. My Dr. said he has never seen this in his career, which of course meant nothing to me. It still doesn't. I spent one day in i.c.u. and four days in step down for this.My back pain was a bad gall bladder..This all happened April 12th.I am doing pretty well controlling things by diet and start cles in the next two weeks. My liver enzymes were high also, so they took a liver biopsy when they did gall bladder surgery. I don't have those #s.
