Hello @freedomwarrior and welcome to Mayo Clinic Connect. I hope that others with concerns about mercury toxicity will join in this discussion.
If you care to share more, this might help me to find others who might be dealing with this. You indicated that you had a positive ANA is that correct? You also say that you believe that it is due to mercury toxicity.
Have you been exposed to mercury at some time? Did your doctor test for heavy metals?
