You should meet 1st any neurologist to diagnose which type of headache you are having so can go accordingly. It may be Tension headache/Cluster headache etc. or Upper cervical spondylosis or VBI also.. After that only can work on it.

Rest, ice packs or a long, hot shower may be all you need to relieve a tension headache. A variety of strategies can help reduce the severity and frequency of chronic tension headaches without using medicine. Try some of the following: Manage your stress level. One way to help reduce stress is by planning ahead and organizing your day. Another way is to allow more time to relax. And if you're caught in a stressful situation, consider stepping back. Go hot or cold. Applying heat or ice — whichever you prefer — to sore muscles, may ease a tension headache. For heat, use a heating pad set on low, a hot-water bottle, a warm compress or a hot towel. A hot bath or shower also may help. For cold, wrap ice, an ice pack or frozen vegetables in a cloth to protect your skin. Perfect your posture. Good posture can help keep your muscles from tensing. When standing, hold your shoulders back and your head level. Pull in your abdomen and buttocks. When sitting, make sure your thighs are parallel to the ground and your head isn't slumped forward.
