A headache becomes serious and requires urgent medical attention if it's sudden and severe (a "thunderclap" headache), the "worst ever," follows a head injury, or comes with symptoms like fever, stiff neck, confusion, vision changes, weakness, numbness, seizures, or difficulty speaking, as these can signal serious conditions like stroke, meningitis, or brain injury. See a doctor right away if headaches change pattern, worsen over weeks, occur with exertion, or if you're over 50 and get new headaches.
See your provider soon if:
Are more severe than usual. Worsen or don't improve with appropriate use of over-the-counter drugs. Keep you from working, sleeping or participating in normal activities. Cause you distress, and you would like to find treatment options that enable you to control them better.
Headaches can be common in early pregnancy. They usually improve as your pregnancy goes on. They do not harm your baby, but they can be uncomfortable for you. A headache can sometimes be a symptom of pre-eclampsia, which can lead to serious complications if it's not monitored and treated.
When the eye and nose on the same side as the head pain are affected, symptoms can include: Swelling under or around the eye (may affect both eyes) Excessive tearing. Red eye.
A pre-stroke headache, often a "thunderclap headache," feels like the sudden, explosive "worst headache of your life," peaking in seconds, potentially with nausea, vomiting, stiff neck, confusion, or vision changes, signaling a medical emergency like a hemorrhagic stroke or TIA (mini-stroke). It's distinct from a gradual migraine, often appearing out of nowhere and accompanied by neurological symptoms like weakness or numbness on one side, difficulty speaking, or balance loss, requiring immediate medical attention (call 911/emergency services).
See a healthcare professional right away if you have visual symptoms that haven't been looked at before, such as: Visual changes in only one eye. Visual changes that last less than five minutes or more than 60 minutes. Visual changes without a headache.
Symptoms of Preeclampsia
A dull, throbbing, migraine-like headache that won't go away, especially when the headache is accompanied by sensitivity to light. Nausea or vomiting that shows up suddenly after the midpoint of pregnancy. Pain in the belly (abdomen), right shoulder or under the ribs on the right side.
Five key warning signs during pregnancy needing immediate medical attention include vaginal bleeding, severe headaches with vision changes, decreased baby movement, severe abdominal pain/cramping, and signs of preterm labor like regular contractions or fluid leakage, as these can signal serious issues like miscarriage, preeclampsia, placental problems, or infection. Always contact your healthcare provider or seek emergency care for these symptoms.
A headache can be triggered any time there is a fluctuation in estrogen levels, including when there is a dip in estrogen levels around the time of your menstrual cycle. Women may also experience more headaches around the start of menopause and when they undergo hysterectomy.
By definition, chronic daily headaches occur 15 days or more a month, for longer than three months. True (primary) chronic daily headaches aren't caused by another condition. There are short-lasting and long-lasting chronic daily headaches. Long-lasting headaches last more than four hours.

Brain tumor headaches tend to cause pain that's worse when coughing or straining. People with brain tumors most often report that the headache feels like a tension headache. Some people say the headache feels like a migraine. Brain tumors in the back of the head might cause a headache with neck pain.
We review the following red flags: (1) systemic symptoms including fever; (2) neoplasm history; (3) neurologic deficit (including decreased consciousness); (4) sudden or abrupt onset; (5) older age (onset after 65 years); (6) pattern change or recent onset of new headache; (7) positional headache; (8) precipitated by ...
Some of the lab tests that may be considered in the evaluation of headaches are: Complete Blood Count (CBC): This test measures various components of the blood, including red blood cells, white blood cells, and platelets. It can help detect conditions such as anemia or infections that may contribute to headaches.
A period headache is a migraine that happens before or during your menstrual cycle. The symptoms are worse than a traditional headache, with throbbing or pulsing head pain, light sensitivity and nausea. Treatment options are available to manage and prevent these headaches.
The "3-2-1 Rule" in pregnancy is a guideline for first-time mothers to know when to call their midwife or doctor for active labor: consistent contractions that are 3 minutes apart, lasting 2 minutes each, for 1 hour (or sometimes cited as 3-1-1, meaning 3 minutes apart, 1 minute long, for 1 hour). For subsequent pregnancies, the 5-1-1 Rule (5 minutes apart, 1 minute long, for 1 hour) is often used, indicating labor is progressing more quickly.
Most pregnancy symptoms don't start until four to six weeks after conception. While many of the symptoms are common, it's possible to experience no symptoms during the first trimester of pregnancy. The most common early symptoms include a missed period, light bleeding, breast changes or tenderness, and fatigue.
Main symptoms
Go to the hospital for a pregnancy headache if it's sudden and severe (a "thunderclap"), doesn't go away, comes with vision changes (flashing lights, blurriness), causes severe vomiting, or is accompanied by sudden swelling in your hands/face/feet, upper abdominal pain, fever, neck stiffness, or confusion, as these can signal serious conditions like preeclampsia. It's always best to err on the side of caution and contact your provider or seek emergency care for concerning symptoms, especially after 20 weeks.
For many years pre eclampsia has been considered to be a two-stage disease. The first stage comprises poor placentation. The second stage is the clinical expression of the disease namely new hypertension and new proteinuria.
A hypertension headache is a headache that happens when your blood pressure becomes very high. People often describe it as a strong, throbbing pain on both sides of the head. This usually occurs when your blood pressure is 180/120 millimeters of mercury (mmHg) or higher. Below 120/80 mmHg is normal.
Depending on where you feel pain, the headache location usually determines what kind of headache you have: Tension headache: Both sides of your head or a band around your head. Migraine headache or hormonal headache: One side of your head. Cluster headache: One side of your head, specifically in or around your eye.
Your eyes offer significant health clues, with yellowing whites indicating liver issues (jaundice), yellow fat deposits (Xanthalasmas) pointing to high cholesterol, and blood vessel changes (kinks, bleeding) signaling high blood pressure or diabetes, while sudden flashes or floaters can mean a retinal tear, and droopy eyelids might suggest muscle disorders, so regular eye exams are crucial for detecting silent killers like hypertension and high cholesterol early.
The 10-10-10 rule for eyes is a simple strategy to combat digital eye strain: every 10 minutes, take a 10-second break and look at something at least 10 feet away, giving your eyes a rest from near-focus on screens. This practice helps prevent eye fatigue, dryness, and headaches by allowing eye muscles to relax and encouraging blinking, which is often reduced during screen use, says Healthline and Brinton Vision.
