See common causes, how likely each one is, and how serious it could be.
A few symptoms worth knowing about.
Sneezing when waking to sunlight
A sudden urge to sneeze, sometimes several times in a row, right as you open your eyes to bright morning light.
Fatigue after eating
Feeling unusually tired or sleepy shortly after you've eaten a meal is common. It often happens as your body diverts blood flow to aid digestion, or it might be influenced by the size or type of meal you've had, like a large, carb-heavy one, or sometimes it points to an underlying condition.
Chest pain when breathing deeply
You're feeling discomfort or a sharp pain in your chest that gets worse when you inhale deeply. This type of pain, often called pleuritic pain, can be due to inflammation of the lung lining (pleurisy), or sometimes it’s a sign of infections like pneumonia, a blood clot, or even a pulled muscle in your chest.
Nausea when smelling perfume
It's that queasy, sick feeling you get in your stomach when you smell perfume. Strong scents can often trigger a sensitive gag reflex or even migraines in some people, and it can sometimes be an early sign of pregnancy.
Nausea after taking vitamins
Feeling sick to your stomach or like you might vomit shortly after swallowing your vitamin supplements. This often happens because some vitamins, especially on an empty stomach, can irritate your tummy or cause blood sugar dips.
Headache at the back of the head
This is a pain felt at the back of your head, often described as dull or throbbing, and it can sometimes spread to your neck. It's usually down to tight neck muscles from stress or poor posture, but we should check it out to be sure.
Sneezing after eating chocolate
Sneezing after eating chocolate means you get a sudden urge to sneeze shortly after consuming it. This can happen if you're sensitive or mildly allergic to ingredients commonly found in chocolate, such as dairy, nuts, soy, or even cocoa itself.
Blurred vision after eating
Experiencing your vision becoming hazy or indistinct shortly after a meal. This can often be linked to rapid changes in blood sugar levels, particularly after eating high-carb meals, or sometimes to digestive responses.
From dehydration to more serious causes worth knowing about.
Headache
Pain or discomfort in the head, scalp, or neck. One of the most commonly reported symptoms across all age groups.
Headache after crying
It's that head pain you get after having a good cry. This can happen because the physical act of sobbing, plus changes in blood pressure and a bit of dehydration, can really put pressure on your head.
Headache after drinking coffee
A throbbing or dull head pain that appears during or after coffee consumption. It can stem from caffeine's direct effect on blood vessels or from your body's reaction to additives like sugar or sweeteners.
Headache after exercise
Pain or discomfort in the head or neck specifically triggered by physical exertion. It is a common occurrence reported by individuals following strenuous activity or high-intensity training.
Headache after flying
It's that uncomfortable head pain you get during or after a flight. This usually happens because of changes in air pressure, not drinking enough water, or pressure building up in your sinuses.
Headache after reading in the car
It's that dull or throbbing head pain that crops up when you try to read or use your phone in a car. This is usually down to your brain getting mixed signals from your eyes and inner ear as the vehicle moves, plus the strain of focusing on a static object in a dynamic environment.
Headache after screen time
A dull ache or throbbing pain that starts or worsens after spending a lot of time looking at computer, phone, or tablet screens. This is usually down to digital eye strain, caused by focusing intensely on bright screens, not blinking enough, and poor lighting.
Headache after sleeping too much
A dull, throbbing, or pounding head pain that occurs after sleeping longer than usual. It's often due to disruptions in your brain's usual rhythm, potentially linked to changes in serotonin levels or dehydration.
Headache after standing
Pain or discomfort in the head or neck that worsens when standing or upright. It is a postural symptom that often improves quickly upon lying flat.
Headache at the back of the head
This is a pain felt at the back of your head, often described as dull or throbbing, and it can sometimes spread to your neck. It's usually down to tight neck muscles from stress or poor posture, but we should check it out to be sure.
Sneezing, congestion, fevers, and other seasonal complaints.

Bloating after drinking milk
Bloating after drinking milk is that uncomfortable feeling of fullness or pressure in your tummy that crops up once you've had some dairy.

Bloating after drinking water
This is that uncomfortable feeling of fullness or distension in your abdomen after you've had a drink of water. It can happen if you drink too quickly, swallowing extra air, or sometimes it's because your stomach is taking a bit longer to empty or you're sensitive to the amount of fluid.
