According to Mayo clinic staff, "A variety of strategies can help reduce the severity and frequency of chronic tension headaches without using medicine."
SIMPLE remedies to try are:
1. Rest/soothing music to relax/proper breathing
2. Ice packs or hot pack (use cold pack or place hot towel or heating pad etc.) Applying heat or ice to sore muscles may ease tension headache. If cold is your choice, wrap an ice pack in a cloth before use to protect your skin. If heat is your choice, you may use a heating pad set on low, a hot-water bottle, a warm compress or a hot towel
3. Long hot shower
4. Manage your stress level: organize & plan ahead. Maintain calender for activities.
5. Perfect your posture: Good posture can help keep your muscles from tensing up. When standing, hold your shoulders back and your head high. Pull in your abdomen and buttocks and tuck in your chin. When sitting, make sure your thighs are parallel to the ground and your head isn't slumped forward.
close your right nose and use your left nose to breathe. In about 5 min, your headache should go.
