20 Years ago I had a brain tumor removed. 18 Years ago I had an arachnoid cyst removed from the back of my brain. 15 Years ago I had a heart attack. I have had no recurring incidence from ether of the problems. From the cyst removal surgery I lost my natural balance. Without visual cueing I am unable to walk without sometimes falling. I have adapted. I was given large doses of steroid. I gained a lot of weight and my pancreas started to function minimally. So now I have type 2 diabetes.
