OH my head!

Yesterday and this morning, I've got a sinus headache like one I haven't had in a long time. It's nauseating. I've done ice, heat, head rub by hubby (which is amazing in itself) taken my allergy meds, Excedrin (which usually knocks my headaches right out) and nothing is helping. It's sorta' weird but I get sinus headaches when the barometric pressure gets up around 30. I wonder if anyone else suffering with sinus headaches has ever paid any attention to this. I checked this morning to see what it's registering and yep, it's 29.87. No wonder I'm dreaming of a little drill for my face and head! When I get these headaches, they start in my face but travel down around the top of my ear to the back of my head and neck... only on my left side always. I had so many things that I needed to get done today and I'm so bummed I woke up with this stupid headache again! It's so hard to function because I feel like a total space cadet. I'll pray it eases up some or I'll end up on the couch all day.
