Friday at work, I worked all day in a different department in a different chair that made me sit awkward and out pressure on my neck. That evening I had a little headache, but figured it would go away once I went to bed. I took 2 regular strength Tylenol Saturday and yesterday, drank tons of water. I realise the pressure moves around now but still nothing is helping. My eyes hurt, it hurts to get up, and more importantly, I'm 9 weeks pregnant. I'm thinking I'd do what I've done in past prior to being pregnant to stop my headaches which is take some Tylenol extra strength with a decaf coffee or a Coke. Any other auggestions? Maybr it's sinus pressure?
