Re: This is driving me nuts!!
I suggest that you get these 2 things tested...
Ferritin & magnesium.
Ferritin = iron stores and is NOT the same as hemeglobin. Most doctors never test this. Optimal ferritin is between 70 & 90 (though the lab reports say as low as 10 is ok, it's NOT & will likely cause low iron symptoms). Low ferritin can cause restless leg syndrome. Find out what your number it. Do NOT settle for being told your is "in range".
Magnesium. Most doctors never test this either. Low magnesium can cause muscle aches and pains, aggitation, twitches, etc.
Both of these can cause heart palpitations too (but not necessarily).
25 years feeling worse every year on Synthroid & 13 months feel good on Armour Thyroid.
