Weird headaches, is this a side effect?

Sometimes,not everyday i get weird headaches. It is not really a typical headache, the ones i usually had. They are more like stings. It feels like a needle would sting my brain on a certain spot. In only one point on my head it stings and it pulses. It stings for a second or two and then it stops for a second or two then it stings again. This usually last for a few minutes then it stops. I also feel pressure in one point of the head. What is this? I never had “headaches” like this before meds.

Could this be a side effect?
