I used my neti pot last night and woke up several hours later with one of the worst sinus headaches I have ever had. I didn't shake the headache until this evening. Nothing was working, and I started to feel really bad from the constant pain. I had similar issues this time last year in that I had a bad sinus headache and congestion but did not have any of the other symptoms I have come to associate with a sinus infection. After three or dour days, it finally passed.
