You are not the first, as you probably know, that suffers this misery due to mercury. I'm 79 and still have all my original fillings but attribute my situation to the shingles vaccine. Of course, this is just conjecture. I recently had a relapse after almost two years of dormancy. Fortunately, it is a fairly small area on my stomach. After trying countless numbers of creams, plain old Cortizone helps to reduce the itching if only temporarily. I read a couple of days ago that ice also helps to quell the itching, so while lying in bed I put some frozen food on the area and left it there for almost an hour. It eliminated the discomfort for the night and I slept. Thanks to anybody who suggested this remedy. I have been reading this site for almost 5 years and this was the first time ice registered as a treatment. Thanks again.
