Hi, can anyone give me a clue as to why I am suffering from sudden sharp head pain above and behind my right ear? It has only occurred in the last couple of days. The pain is coming often, sometimes several times a minute, its very sharp, makes me wince and catch my breath and is then gone. There is no warning and is worrying me. The area is beginning to feel bruised, without being poked about. Sometimes, the pain shoots into the neck down behind my ear. Generally I am in good health, I am of average weight, 25 yrs old. I have been quite tired recently and have noticed in the last couple of weeks some muscle and joint soreness and stiffness. Please help me on this.?
