A tension headache is a common type of headache characterized by a dull, aching pain and a feeling of tightness or pressure around the forehead or back of the head and neck. It often results from stress, anxiety, or muscle tension, and can last from 30 minutes to several days. These headaches can occur episodically or become chronic, affecting daily activities. While they are not usually severe, they can be uncomfortable and may be accompanied by sensitivity to light or sound. Over-the-counter pain relievers, relaxation techniques, and lifestyle changes can help manage symptoms.
