I have also been suffering for years off and on, with every doctor I've seen, completely dumbfounded and perplexed.My symptoms have been so bizarre, and varied so much, but lately have centered on chest pains and pains in my arms, irritation in throat, and occaionally tips of my fingers.The angina has reached a truly frightening level as of late.What I don't get is that if it is linked to Mercury,which is in my mouth, why would it be off and on and not all the time?
