I m currently 24 weeks pregnant and have been dealing with a terrible sinus infection for 6 days. I felt a little better yesterday but today any time I sit or stand I get a debilitating pounding headache. I have a high pain tolerance but I literally have to squeeze my hands around my forehead to keep from feeling like my brain in going to explode. I feel like it is low blood pressure but I m drinking like crazy and having to use the bathroom a lot (which I d rather not do since I want to die when I stand). I still have a bad headache while lying down but I m not sure if that s from the sinus pressure. It s much less severe and doesn t pound as much. I m maxing out on Tylenol and not sure what else to do!
