How can patients be patient when they don't feel good and doctors say that they won't feel better for months!
I'm going to have to disagree with the doctor on this one! It does not take months to see benefits from thyroid meds or vitamin D supplementation!
Many cardiologists (yes, cardio not endo) say that they prefer the natural meds like NatureThroid instead of ones such as Synthroid. FYI Did they feel your thyroid? Did they run the thyroid antibodies?
Find a good vitamin D3 (5000 IUs) supplement. Capsules will absorb better than tablets.
Did they check your B12 as well?
So many of us have more than one thing going on. At least the D and thyroid issues are more easily fixable than MG (with less or no side effects).
If you start having GI tract issues, have them test for celiac disease! LOL
I hope you feel better soon!!!
