Multiple factors can bring on a tension headache, including stress, inadequate sleep, and poor posture.
The main symptom is pain on both sides of the head that may be associated with muscle pain.
Treatments include pain relievers and other medications. Stress reduction, ice or heat on sore muscles, and good posture also may help.
