I get "eye aches too" and have for about 6 years. I have Hashimoto's thyroiditis (autoimmune hyOthyroidism) but my dr. says the eye pain is a Grave's thyroiditis (autoimmune hypERthyroidism) symptom. I think it's mercury. I had my fillings replaced and am waiting to, hopefully, see these symptoms disappear, along with the light sensitivity and double vision that accompany the eye pain.
