Pulsating in your head means feeling a robust rhythmic sensation in the head. It mostly turns to a throbbing headache if it does not go in a short period. Throbbing headaches are prevalent and can occur with migraines or tension headaches. Periodic throbbing in the head that responds to pain relievers such as Aspirin, ibuprofen, or paracetamol is usually harmless. Throbbing headaches can also occur as part of a sinus or frontal sinus infection. But, if you have headaches more than eight times a month, you should let your doctor check it out.
