Hello sir, I'm suffering with headache from more than a year and simply took medicine to cure it. But now days its increasing day by day. I feel nauseous, memory issue and have pressure in eyes, I feel very confused and sad all the time. I feel dizziness all the time. I m suffering with thyroid also but its very nominal. Around 6. But this headache is turning me off. Please suggest me sir is it due to thyroid?
