Given the location of your headaches—around your left eyebrow, eye, cheeks, and upper teeth—it’s understandable that you’re trying to figure out what might be causing them. The pulsating sensation and the way they seem to be triggered by certain activities, like using your phone while lying down, can provide important clues. While it’s good to hear that your eye exam and MRI came back normal, it’s still important to consider other potential causes. Trigeminal neuralgia is one possibility, especially since it affects the areas you mentioned and can present with sudden, intense pain. However, other types of headaches, such as migraines or tension-type headaches, could also be at play. Track Your Symptoms: Keeping a detailed headache diary can help identify patterns, triggers, and any associated symptoms. Note when the headaches occur, their intensity, duration, and any activities that seem , factors like screen time, posture, and stress can contribute to headaches. When using your phone or watching something, try to take breaks, adjust your position, and ensure good lighting to reduce strain. It’s important to keep advocating for your health, especially when something doesn’t feel right. I hope you find some clarity and relief soon!
