Aches and pains you should never ignore

Pain is your body’s way of telling you something’s wrong. Sometimes you’ll know exactly why you’re hurting: If you went hard at the gym yesterday, it’s no surprise you’re sore today.

But sometimes pain is symptomatic of a more serious condition. Be aware of these seven aches and pains that may require medical treatment right away.

If you have: A severely stiff neck, affecting your ability to bend your head forward or to the side

Especially with: Fever and chills, nausea and vomiting, sensitivity to light, confusion, lethargy, or headache

It could be: Meningitis

Meningitis is inflammation in the tissue lining of the brain and spinal cord (the meninges). The inflammation can cause a variety of issues, including seizures, hearing loss, disability, brain damage, and even death. The two most common of types of meningitis are viral and bacterial. Viral meningitis is more common and less severe. Bacterial meningitis requires immediate hospitalization.

If you have: Chest pain or discomfort

Especially with: Shortness of breath, nausea, vomiting, back pain, or pain in the arm, shoulder, or jaw

It could be: A heart attack

Intense chest pain and pressure is the most common symptom of a heart attack. Cardiologists say the sooner a patient receives treatment for a heart attack, the better off they’ll be. Ideally, patients will receive treatment within 60 minutes of the onset of symptoms. It’s important to know the signs of a heart attack, so you can take action.

If you have: A zit that hurts

Especially with: Redness around the infection site or fever

It could be: Staph

A painful, throbbing zit, especially if you’ve had an open wound or close contact with another person, could indicate an infection of Staphylococcus aureus, or a staph infection. It may look like a pimple, but staph is a bacterial infection that usually spreads by skin-to-skin contact. There is a form of staph called methicillin-resistant Staphylococcus aureus (MRSA) that’s harder to treat than normal staph. Severe MRSA infections that move to the bones, joints, or bloodstream can be fatal.

If you have: An agonizing headache, or the worst headache you've ever had

Especially with: Dilated pupil, vision changes, nausea, numbness, weakness, or paralysis of one side of the face

It could be: An aneurysm

Headaches have many causes. But a headache you feel above and behind one eye could be a sign of a brain aneurysm, which is the swelling or ballooning of an artery in the brain. High blood pressure, high cholesterol, and smoking are risk factors. Small aneurysms usually don’t cause symptoms. Larger or burst aneurysms cause a headache.

If you have: Pain in the leg, especially the calf

Especially with: Warmth, swelling, tenderness, or skin color of the leg appearing red or purple

It could be: Deep vein thrombosis

It’s been said that sitting is the new smoking, which goes to show how a sedentary lifestyle can affect your health. If you’ve been sitting for a long time without getting up—at work, in a car, on a plane—and your thigh or calf starts to hurt, it might be a sign of deep vein thrombosis (DVT). It’s a blood clot that can travel to the lungs, causing a blockage of a lung artery called a pulmonary embolism. Your risk is highest after major surgery, severe injury, or if you have heart failure, a heart attack, or cancer.

One way to lower your risk of DVT: Get up and move around every hour, even if it means stopping the car.

If you have: Severe lower back pain

Especially with: Blood in your urine, pain while urinating, fever and chills, vomiting, or urine that’s cloudy or smells bad

It could be: A kidney stone

Back pain is one of the most common medical problems, affecting about 8 in 10 people at some point in their lives. It has many potential causes, but one more serious cause is kidney stones. Kidney stones form when substances in urine become highly concentrated and solidify. Small stones may pass through the urinary tract on their own, but large stones can get stuck, resulting in severe pain. More than 500,000 people go to the emergency room every year for kidney stones, according to the National Kidney Foundation.

If you have: Sudden pain in the right side of your belly, or pain around your belly button that migrates towards the right side

Especially with: Swelling of the abdomen, fever, loss of appetite, nausea and vomiting, constipation, or diarrhea

It could be: Appendicitis

Often, a bellyache is simply caused by eating too much. But if you have sudden pain in the right side of your abdomen that gets worse over time, it could indicate appendicitis. It's a condition in which your appendix becomes inflamed or infected. Appendicitis is almost always treated with removal of the appendix and is more common in people between 10 and 30 years old.
