Hi I am 34 years old female. I am having thyroid medicine 88 mcg daily morning. I am getting blurred vision for nearly half an hour and after that heavy headache for for hours. I am getting this very often but suddenly. Sometimes when I was looking out for sometime ,after sunlight hitting my eyes, suddenly getting blurred vision. Immediately feeling so tired too. I am totally confused and scared of this. After I can't do anything for sometime. Please guide me a solution so that it will be more helpful. Also please guide to whom I have to consult eye doctor or internist.
