I've been reading about all these side effects and can identify! I've a 2 seperate episodes of what I thought was nerve issues, 5 years apart, both postpartum. Have had tingling and numbness in feet, hands, lips, and tongue, and have as well been tested for ms. I also am having vision issues, eyes don't focus like they're supposed to. FYI- some people do better on synthroid, and some on levoxyl. I personally felt even worse on synthroid the one time I tried it.
