I recently started using the Neilmed sinus rinse bottle. I have chronic congestion from my allergies, and the sinus rinse cleared my air passages beautifully, but I developed headaches as soon as I started using it. The headaches are concentrated just behind my eyes and forehead, like an upper sinus headache. Has anyone else experienced this, and if so has a physician explained why?
I wonder if some of the fluid is getting stuck up in your sinuses and not draining. I have had that happen when my sinuses are inflammed, gives me a bad headache afterwards. Try taking an anti-inflammatory such as ibuprofen, that might help release the fluid. Do you regularly have sinus problems? Have you ever been seen by an ENT?
