I am doing a lot of computer work these past few weeks. My time is consumed in front of the computer. I experienced headaches. Today I had one that is pulsating. What I did to ease the pain were: I relaxed and stay away from the computer for a while, drank water and lightly tap my scalp for a few seconds, took slow deep breaths. I felt better. It softened tensed muscles in my head and neck and it built my energy. Then back to work again.
