It’s that time of year again. You wake up one morning achy and tired, with a scratchy throat and a nagging cough. “Just a cold or a touch of the flu,” you think as you prepare for an uncomfortable day. But the cough hangs on and on, as one day eventually becomes one week and then two. Now what?
Vague symptoms often make it tough to know what’s behind them and whether it’s time to see a physician, such as when a cough lingers for weeks or achy joints become swollen and inflamed. Here’s how to tell the difference between a passing symptom and one that calls for a medical evaluation.
If you find yourself rubbing your temples by the end of the workday you’ve got plenty of company. Headaches often bring patients to a neurologist’s office, says Ravinder Singh, MD, neurologist and president of Premier Neurology Medical Group in Beverly Hills, California.
“Tension-type headaches are the most common and affect nearly 40% of the population,” he notes.
A 2014 American Academy of Neurology study of more than 5,000 people between 21 and 71 showed that 31% experienced tension headaches. Those with tension-type headaches rated their stress at an average of 52 out of 100; migraine sufferers reported their stress at 62 out of 100.
“Most headaches do not have an underlying cause and are labeled primary headaches,” says Singh. Among symptoms that imply an underlying, secondary cause such as a tumor, infection or bleeding is a headache that reaches peak intensity within seconds or minutes, or feels like the “worst headache” of your life.
Likewise, there could be an underlying cause if you have a headache triggered by:
- Bending over
- Sexual activity
- Other physical exertion
- A headache that starts or increases after trauma to the head or neck
Another possible cause for concern are headaches with neurological symptoms, such as:
- Speech difficulties
- Balance problems
- Visual changes
- Numbness or weakness, especially on one side of the body.
A headache accompanied by memory loss or confusion, as well as that associated with fever or neck stiffness, should be checked out. The onset of headaches after age 40 or for the first time in any patient, Singh says, also may indicate some root problem.
“If you have one of these symptoms it doesn’t mean you have a life-threatening underlying cause,” says Singh. “It just means that we need to look carefully so that we do not miss an underlying cause.” See a physician for an evaluation.
As with headaches, a cough can crop up on its own or be among a group of other symptoms.
Coughing may be due to:
You want to consider several factors when looking for reasons behind a cough, according to Mary Beth Miller, MD, an internist specializing in family medicine in Torrance, California. “I look at the season, since a lot of different things are out there at different times of the year such as allergies or cold and flu,” Miller says. She explains that the age of the person also needs to be taken into consideration.
The person “may be immune-compromised, such as in cases of chemotherapy treatments,” Miller adds. “But usually a cough is due to a virus or possibly allergies.” A virus will run its course in 7 to 10 days, while a cough due to allergies can vary in length.
Acute coughs typically begin suddenly and accompany a cold, flu or acute bronchitis, and last between two to three weeks. Chronic coughs lasting longer than this time may be due to allergies, asthma, chronic obstructive pulmonary disease (COPD), GERD or as a side effect of some medicines.
“A cough that does not go away within 10 days should be checked,” says Miller. A secondary bacterial infection may be at work, or the person may have underlying asthma and not know it.

Sore throat symptoms vary depending on the cause and may include:
- Pain or a scratchy sensation in the throat
- Difficulty swallowing; dry throat
- Sore swollen glands in the neck or jaw
- Swollen, red tonsils
- White patches on the tonsils
- Sore throat accompanied by a hoarse voice
“In the same way coughs usually run their course, a sore throat typically clears up within three to five days,” says Miller. A viral infection causes the majority of sore throats, such as those caused by a cold or flu. The age of the person may provide signs as to the cause of the symptoms, says Miller, noting that a sore throat in a teen may be a sign of mononucleosis, a viral infection, but be due to something else in an older adult.
“A sore throat on its own without any other symptoms may be strep throat, says Miller.”
Caused by bacteria, strep throat requires treatment with antibiotic drugs. Signs you should seek immediate care for a child with a sore throat include difficulty breathing or swallowing and unusual drooling, which may indicate an inability to swallow. Adults with sore throats lasting longer than a week should also seek medical attention, especially if the sore throat is accompanied by a fever, upset stomach and/or swollen glands.
Other signs of a possible more serious underlying cause in adults include:
- Difficulty swallowing or breathing
- Inability to open your mouth
- Joint pain
- Fever higher than 101°F
- Blood in the saliva
- Frequently occurring sore throats
- A lump in your neck
- Hoarseness lasting more than two weeks
“Left untreated the body’s immune system will almost always take care of itself,” says Miller. “But when you don’t take care of the infection you could risk damaging your heart valves or kidneys, although the likelihood is rare.”

For symptoms of dizziness, you want to distinguish between light-headedness or feeling faint versus vertigo, says Allen Towfigh, MD, a neurologist affiliated with Weill Cornell Medical Center/New York Presbyterian Hospital in New York City. “The latter refers to the sensation that one’s surroundings are moving when they are, in fact, standing still,” Towfigh says.
Vertigo may be caused by crystals inside the ear dislodging and sending the brain mixed signals. Known as benign paroxysmal positional vertigo (BPPV), this can trigger significant nausea and vomiting, says Towfigh. On the other hand, vertigo associated with Meniere’s disease is due to an inner ear dysfunction and typically links with tinnitus (ringing in the ears) and hearing loss. Double vision, muscle weakness and trouble speaking along with vertigo may indicate a stroke.
In contrast, light-headedness or feeling faint is a less descriptive term with a longer list of potential causes such as dehydration, according to Towfigh. “Medications can also commonly cause light-headedness and feeling faint,” he says. Other possible causes include a drop in blood pressure due to an abnormal heart rhythm (arrhythmia) or a change in body position, such as when standing from a seated position.
“It is important to investigate vertigo and light-headedness to determine whether changes need to be made to medications or dosing and to ensure there is no cardiac abnormality,” Towfigh says.
Your back may ache after a day of shoveling snow, moving furniture or as a result of slouching and otherwise going about your day in poor posture. From a constant, dull ache to a sudden pain, 8 out of 10 people can expect to experience back discomfort at some point in their lives.

“Age, arthritis and disc degeneration often play a role in back pain,” says Towfigh. Scoliosis, an improper or exaggerated curve of the spine, or narrowing of the spinal canal or the foramina where the nerves exit (spinal stenosis and foraminal stenosis respectively), may also contribute to discomfort, he notes. Fortunately, most back pain goes away on its own over time.
Severe pain lasting longer than three days or back pain following an injury—such as from falling from a height or from a hard, ground-level fall—should be checked by your healthcare provider.
In addition, seek medical attention if you experience a sudden onset or dramatic increase in the level of pain. “This can be a sign of a disc rupture or herniated disc, or a compression fracture in older adults or those suffering from weakened bones (osteopenia/osteoporosis),” says Towfigh.
Pain traveling down one or both legs, a possible sign of nerve compression (sciatica), is another reason to seek medical attention. Weakness or difficulty walking or going up and down stairs may also indicate nerve compression.
Finally, see your healthcare provider if pain worsens at night or while lying flat. Pain felt when lying down, especially when the pain starts when lying down, may indicate disc degeneration, a sprain or fracture, kidney stones or various forms of arthritis, and should always be evaluated by a medical professional.
A common complaint (especially with advancing age), joint pain often is the result of simple wear and tear, notes Steven Gausewitz, MD, Chief of Staff at Hoag Orthopedic Institute in Newport Beach, California. “Most joint pain can be treated with ice or over-the-counter pain relievers and rest, or eases up with weight loss,” Gausewitz says. Limping, difficulty getting around, and being disabled by joint pain may indicate that it’s time to visit your health care professional for a medical evaluation.
Pain can also be a sign of an infection in the joint, says Gausewitz. “The pain is acute and extreme, and you can’t move the joint at all, which indicates it’s time to see a doctor.”
Infections can result from bacteria in the blood for an unknown reason, which is a relatively rare occurrence. Joint infections can also stem from seemingly unrelated issues in other parts of the body (such as a lung or a urinary tract infection), according to Gausewitz. “Joint pain due to inflammatory or rheumatoid arthritis should also be evaluated and treated by a doctor.”
Feeling tired and fatigued is not only a very common symptom but also one of the hardest to figure out, says Miller.
“Fatigue could indicate anything from cancer to heart disease but is most often simply sleep deprivation,” she says.
Lifestyle habits, psychological conditions and certain health issues can all result in fatigue. For example:
- Alcohol use or abuse
- Excessive physical activity or lack of activity
- Not enough sleep
- Unhealthy eating habits
- Medications such as cold and cough medicines or antihistamines
Screening for the cause of fatigue starts with looking at the most common physical concerns that may be causing it, says Miller. “We screen for issues that are easy to determine, such as sleep apnea and depression; then we move to the lab,” she says.
“Medicine is not black and white,” Miller adds. “It often takes a lot of time to figure out what’s causing the symptoms.”
