Well mercury is a strange poison. Many people who have had DMPS injections appear to tolerate them fine time after time, but then sometimes will have an adverse reaction that seems to cause irreversible damage...even though they tolerated the same dose many times before.

It certainly sounds like something went wrong and you got some sort of irreversible damage, but I just don't like to think that way, as there is always some hope that things will get better, even if it requires a miracle.
