Q. I get acute pain on either side of forehead. Could this be a sign of brain cancer?

Hello doctor,

I experience small pains that last for a second on both sides of my forehead. I have experienced it for many years since I was a child, but I did not think much about it since it did not interfere with my life, and I thought it is normal. I can carry out my normal activities as well. Sometimes biting and chewing and moving my head in general would trigger these pains. When I am exposed to cold air conditioning, I feel pressure in my head, and when I bend down, I feel a bit of pain on one side of my forehead, but it goes away instantly. My best friend has been diagnosed with brain cancer, and I am anxious whether I have something similar. I usually worry about my health a lot. I visited a doctor a year ago, and she told me that I might not have enough sleep enough and probably I have phlegm/sinuses. The pains do not bother me significantly, but I wonder if something is wrong, whether it is normal or not. I am scared to go to the doctor because my family would think that I am lying and wasting their time. I have heard that an organ's proper functioning would sometimes trigger pain, which are normal, so I wonder if it is that is the case. Should I go to a doctor again for proper evaluation?
