Hello I also have had bouts of these electrical pains in my head that go off every few seconds all day long and landing me in the emergency room crying in pain. I finally found the right person who had actually experienced it themselves and said to use Biofreeze on my neck and in the back of my head all the way up to my ears on each side. This is not an actual headache it is from the nerve and the nerve needs to be released from the muscle as soon as I put Biofreeze on my neck they start happening
