For the past week or so I have been experience a pain in the back of my head sometimes on the right side. It also causes some neck pain. I believed it to be a tension headache but the medicine I took wasn't helping. I decided to try sinus medicine since I do have bad sinuses and the weather has been changing and that seems to work but the headache comes back. It usually comes towards the middle of the day and varies from a dull pain to a stabbing pain when I move my head or neck around. Could this be sinus related even if it is in the back of my head? It is very agitating and I am experiencing a little congestion and my ears have been popping. Please help! Thank you in advance.
