The first thing that you need to do is to have your amalgam fillings removed by a dentist that takes special precautions to keep you from getting even more poisoned.

After that you need to start on some type of chelation therapy to detoxify your body. I have taken IV DMPS infusions but the side effects can be severe and it is expensive. Other people use DMSA, alpha lipoic acid, or various natural chelating agents. You have to find what works best for you.

I recommend that you buy Andy Cutler's book on amalgam illness.

52 indicates that you probably have a huge amount of mercury in your body. I was in the "very elevated" range with numbers in the 20's and I am terribly ill.
