You’re sneezing and sniffling, with a stuffy nose and an itchy throat. With these kinds of symptoms, you probably have a cold. Then again, allergies can cause similar symptoms. So which one is it -- a cold or allergies?
Before you open your medicine cabinet and start to search for relief, you need to know which type of medicine you need. Colds and allergies need different types of treatment.
When you're not sure what the problem is, try these three simple tests. They'll help you figure out whether you've got an allergy problem or just a typical cold.
Cold vs. Allergies: What Are Your Symptoms?
A runny nose and sneezing won't tell you whether you have a cold or allergies, because they can be signs of either condition. But some symptoms are unique to either colds or allergies.
To help you decide, check your symptoms against this list:

What's the Season?
If you're sneezing and sniffling in April and your car is coated with yellow-green pollen, you may be able to point to an obvious cause: seasonal allergies or hay fever. This is especially true if you get the same symptoms at about the same time every year.
Colds can hit at any time of year -- even during spring and summer -- although they're most common when the weather gets chilly.
How fast your symptoms occur can also determine what's ailing you. Allergies often start almost immediately after you're exposed to your trigger. For example, if you've got pollen allergies, as soon as that pollen makes its way up your nostrils, you may have symptoms.
Cold germs typically take 1 to 3 days to make you sick. If your nose is starting to twitch and you realize you were sitting next to a sneezer at the movie theater 2 nights ago, a cold may be the cause.
Colds generally linger for 3 days to about a week, but symptoms can last up to 2 weeks in some people. Starting to feel better after a couple of days is a sign you're probably on the mend from a cold.How Long Have Your Symptoms Lasted?
If you're getting worse, your cold may become a bacterial infection. If symptoms last more than 1 to 2 weeks or get worse after about 5 days, you should see a doctor.
Allergy symptoms will last for as long as you're exposed to your trigger. So if you're allergic to cat dander, once you say goodbye to your grandmother and their prized Persian cat to return home, your sniffles should subside. If your trigger is pollen and you spend most of the spring months outdoors, you could be facing symptoms for the whole season.

Rhinitis is when a reaction occurs that causes a stuffy nose, runny nose, sneezing, and itching. Most types of rhinitis are caused by an inflammation and lead to symptoms in the eyes, ears, or throat. There are several types of rhinitis. The most common types of rhinitis are:
- Acute rhinitis, which is often caused by a viral illness
- Allergic rhinitis (can be seasonal or year round)
- Nonallergic rhinitis
Allergic rhinitis is caused when allergens in the air trigger the release of histamine in the nose and sinuses. Histamine causes itching, swelling, and fluid to build up in the fragile linings of the nasal passages, sinuses, and eyelids.
What causes rhinitis?
The most common causes of rhinitis are:
- Pollen given off by trees, grass, and weeds
- Dust mites
- Mold
- Cockroach waste
- Animal dander
- Fumes and odors
- Extreme temperature or changes in temperature
- Hormonal changes
- Certain medicines and overuse of topical nose sprays
- Changes in the environment
- Irritants such as strong odors and tobacco smoke
- Certain foods or spices
Who is at risk for rhinitis?
People with asthma are at a higher risk for rhinitis. Allergic rhinitis is a common problem that may be linked to asthma. But this link is not fully understood. Experts think that since rhinitis makes it hard to breathe through the nose, it's harder for the nose to work normally. Breathing through the mouth does not warm, filter, or humidify the air before it enters the lungs. This can make asthma symptoms worse.
Asthma and allergies are also caused by many of the same chemical triggers in the body.
Controlling allergic rhinitis may help control asthma in some people.
What are the symptoms of rhinitis?
Symptoms of rhinitis include:
- Sneezing
- Stuffy nose
- Runny nose
- Itchy nose, throat, eyes, and ears
- Nosebleeds
- Clear drainage from the nose
- Ear infections that keep coming back
- Snoring
- Breathing through the mouth
How is rhinitis diagnosed?
Most often, the diagnosis is made by your healthcare provider based on a full health history and physical exam. In addition to the above signs, the healthcare provider may find:
- Dark circles under the eyes (more common in children)
- Creases under the eyes
- Swollen tissues inside the nose
- Mouth breathing
How is rhinitis treated?
Staying away from the allergens that are causing the problem is the best treatment. Sometimes it can be hard to stay away from triggers (including allergens), such as pollens. The symptoms of rhinitis sometimes look like other conditions or health problems. Always see your healthcare provider for a diagnosis.
Treatments for rhinitis may include:
- Antihistamines
- Nose sprays
- Decongestants
- Medicines for asthma symptoms
- Allergy shots
- Surgery for some health problems
Can I prevent rhinitis?
Preventive measures depend on what triggers your rhinitis. These can include:
- Staying away from areas where there is heavy dust, mites, or molds
- Not being around pets
- Staying away from what you know you are allergic to, or what triggers your rhinitis
- Controls in your environment, such as air conditioning during pollen season
- Staying away from people who are smoking
- Staying away from strong odors and irritants when possible
- Using nose sprays only for the prescribed length of time
Key points about rhinitis
- Allergic rhinitis is a reaction that happens in the eyes, nose, and throat when allergens in the air trigger histamine to be released in the body.
- Some of the most common causes of allergic rhinitis are pollen, dust mites, mold, cockroach waste, animal dander
- Nonallergic rhinitis is inflammation in the nose, eyes, and throat from nonallergic sources such as fumes and odors, hormonal changes, and smoke.
- Symptoms of rhinitis include sneezing, stuffy and runny nose, nosebleeds, and itchy throat, eyes, and ears.
- Treatment may include medicines, allergy shots, and surgery for some health problems.
- Preventive measures for rhinitis include staying away from what you are allergic to and avoiding your triggers.
