Hi I did review your concern. Sometimes it becomes difficult to differentiate between headache due to migraine and headache due to sinus infection. The important clinical differentiating point is that headache due to sinusitis generally also has concomitant pain when pressed over the sinuses. You can check that yourself by pressing on both sides close to your nose and above your eyes for sinus tenderness. Another evaluation is sinusitis is CT scan of paranasal sinuses. Also if ELAVIL and neurontin are not working it is more likely for sinus headache than migraine. I would recommend you consult a ENT doctor and get your self evaluated for sinus infection and management of sinus drainage. I hope this helps. Wish you all the best. Thank you for choosing healthcaremagic.
