Tension-type (occipital) and cluster headache are usually treated with NSAIDS and muscle relaxant as an initial treatment options. Triptans reserved for the cases when initial treatment does not relive the pain. Botox injection plays a big role in current medical management for the treatment of tension-type headache. For the treatment of occipital headache the first line of treatment is pharmaceutical, and the second line of treatment is steroids and/or Botox injection to relive the muscle spasm damaging occipital nerves. The third line of treatment which is the most effective treatment of occipital headache in today days is peripheral nerve stimulation.
