Nina,

Yes, because they will cause a cleansing effect, I think it may make symptoms worse before they get better so you may want to make a judgement call as to whether you feel strong enough to go that route.

Come to think of it, I remember having occasional kidney pain before my amalgams were out and through experimentation, I found that certain "bad" foods caused the pain to occur. Finding and eliminating the bad food perhaps may be the key.
