MEN llA and adrenaline tumers?

Hi, I have a genetic cancer called MEN llA and had surgery to remove my thyroid in 2005, recently I have been getting extream headaches, adrenaline rushes, anxiety attacks, pressure on my chest, dizzyness ( almost to the point of fainting), very fast heart beat, palpitations, nearvousness, shaking really badly, and sometimes a sharp pain in my chest on the left side, my blood pressure is fine though. Im worried because I know that with my cancer there is another kind of cancer that I can get where there are tumers on the adrenaline glands. I wanted to know if these sound like the symptoms I would have for that. right now im taking synthroid .150 mg and I havent been tested for my lvls since March 08. please get back to me.

thanks
