Chronic headaches : It sounds like you are suffering from chronic headaches or chronic migraines (because of the nausea). If the thyroid hormone levels are off that can also cause headaches; talk to your endocrinologist about it. You would benefit from seeing a headache specialist too. Home remedies that you could try are warm compresses on neck and temples; magnesium supplements and herbal tea.
