Sinus problems can cause headaches that come and go. They may be mild or severe. Since the sinuses go across various nerves, when they become inflamed, they can press against those serves and cause headaches. Over the counter medications can help reduce the pain. Medications that help reduce inflammation can also help reduce the swelling inside the nose and sinuses can relieve the pressure that can cause headaches.
Many people also feel pain behind their eyes caused by sinusitis that can turn into a headache. Turning the head quickly from left to right, bending over and looking down, and standing up quickly can make the pain of the headache worse and also cause dizziness. Blowing your nose can also help reduce the pressure in the sinuses and relieve headaches. If over the counter pain medicine doesn’t seem to be working, talk to a doctor about prescribing something stronger for the pain.
