I personally think your just very stressed ... another possible factor would be your diet and also some high quality games can make your head hurt too ... I know most of this through experience and as our family has a legacy of having migraines XD and I personally suggest going easy on the pain killers boss.
also I think it goes something like this : general pulsing pain = high blood pressure, pain on the back of the head = too much gaming =( or too much visual info, pain concentrated on the front part = too much thinking/stress
