Sinus headaches are a typical symptom of sinusitis, a disease in which the sinuses become inflamed due to allergies or other causes such as an infection. Seasonal allergies that linger for a lengthy amount of time can also cause sinus headaches. This is known as rhinitis, often known as hay fever. Other factors that may be responsible for sinus headaches include smoking, drinking alcohol excessively, using drugs such as cocaine and amphetamines, and taking certain medications such as anticonvulsants and immunosuppressants. Headaches are the most common symptom of a sinus problem. They can be severe, frequent, and last for several days. Symptoms include pain behind the eyes, inside the head, or forehead. These symptoms may be associated with other problems, such as hearing loss or facial swelling. Sinus headaches can be treated effectively if they are identified early. It is important to see your doctor if you suffer from recurring headaches of any kind. He or she will be able to diagnose which type of headache you have and suggest the best course of treatment.
