I have been going to my doctor since last spring about my dizziness, and everytime they check my blood sugar and iron. It's always be normal. The past few months it has been getting worse to where I will start shaking and sweating. I bought a blood sugar monitor, and try to check my sugar every time I have an "episode", but it's always normal. The doctor does not want to run anymore test because he thinks that I am fine. I know something is wrong with me, and really think it's a neurological thing. What do you suggest I should do?
