I have a rippling sensation in the brain

I have had a weird rippling sensation in my brain behind my right eye and above the ear in that area. It never just happens once and occurs maybe around 5-10 times. When it begins I feel a pressure which ends up with me instinctively having to close my eye. After I've closed my eye the feeling happens it only happens for around 2 seconds but it isn't just one feeling it is like multiple pulse ripples in just one of the sensations. It doesn't hurt but it's weird and causes my head to shake. Is this natural could it potentially be just a lack of blood flow or my brains response to the light or something like that. I haven't been to the doctors in years and I don't want to waste there time with something as mild as maybe a headache or something. It doesn't feel like a headache or migraine it lasts for like 2 seconds and I'll be fine then 2 minutes later it will repeat. I'm only worried because it's a feeling in the brain.
