i don't know too much about the thyroid...but from experience i have seen many MANY people with autoimmune arthritis AND throid problems.
mine for instance is hypothyroidism...supposed to be on Synthroid but my heart was just too jumpy out of control on it.
keep close communication with your docs.
take good care
