Hi, I am one month post TT. I still have a few weeks before my levels will be checked. I seem to have a constant headache. It hurts more in the back of my head near the base of my neck. I also have lots of dizziness!! It's almost that feeling when you have been on a plane for a long time - motion sickness with out the nausea. Or I could say it feels very similar to when you have a sinus infection or head cold and feel woozy, but I don't have either. If this would go away, I would feel so much better. Any ideas on what could be causing this?
