When to seek help
Brain freezes vary from mild to severe. Your situation is mild if you experience a brain freeze just while you are enjoying a cold drink, in this case, you do not need to see a doctor. But if the headaches have become more regular, you should contact your doctor for a prognosis. Both brain freeze and severe headaches disorders such as cluster headaches are traced to the same nerves. Recent findings have identified a possible link between the intake of cold substances and atrial fibrillation (AF) [4], which is a type of arrhythmia, or irregular heartbeat.
Although this connection is rare, if you start to experience irregular heartbeats when you consume cold food or liquid, call your doctor immediately. You might need to go to the hospital for evaluation and diagnosis. You should reach out to your doctor if the pain felt lasts for up to 5 minutes either with or without treatment. If you experience similar pain and you haven’t had anything cold or stayed in a freezing environment, you should immediately contact your doctor.
