I used to be headache champion! I don't think anyone ever understood why they happened. Sometimes, low air pressure was clearly a suspect.

Sometimes a temple would hurt as if someone had tried to drive a nail into it. Sometimes it felt as if someone had attached a winch to my neck muscles and was trying to pull my head off backwards. I suspected that aching muscles caused these pains. Then a nurse told me about Aspercreme. It worked! I would rub it on the affected part and get relief with no fears of an upset stomach.

I suggest you try it. I also suggest drinking plenty of water, as suggested.
