Pain in my head

I'm having headache behind my right head for the past few days. I was wondering what is wrong. Did some research over the net last night ans the result is not convincing and yet make me relieved. I guess I need to consult the doctor but I don't want to be admitted. I can't afford another hospitalization after the last one which caused me away from the office for more than a week due to gallstones.

Hope the pain would ease away by tomorrow morning. I pray to Allmighty to heal the pain. Amen.
