Do you feel an odd pain on your nape sometimes? It feels like there is some kind of an object weighing around two or more kilos put on your nape. That is tension headache for me. I experienced it for the very first time when someone very close to me left us. Since then I had not felt anything like that. Thank God! I therefore conclude that tension headache develops from a deep emotional burden that could not be cured until you finally accept the situation.
