This can cause cold-like symptoms. Many people have allergies to both indoor and outdoor substances, such as pet dander, pollen, and dust mites. Allergies can be seasonal or last all year long. They can cause an irritating inflammation in your nose that may give you a tickly, itchy feeling.

The air-filled sacs behind the nose are called the sinuses. Colds can lead to sinus infections when the sinuses swell up. Air, mucus, and bacteria can become trapped in the swollen sinuses and cause further infection. The main difference between a cold and a sinus infection is the duration of symptoms.

An allergy is an inflammatory immune response to specific foods or something in the environment, known as an allergen. Colds and flu are caused by viruses or bacteria. Therefore, a cold or flu cannot cause an allergy. Sometimes, allergies can lead to a sinus infection, which may develop into a fever.

Colds can lead to sinus infections when the sinuses swell up. Air, mucus, and bacteria can become trapped in the swollen sinuses and cause further infection. The main difference between a cold and a sinus infection is the duration of symptoms. Most people recover from a cold in 5 to 10 days.

How does an ADR differ from a side effect or allergy? An allergy is an adverse drug reaction mediated by an immune response (e.g., rash, hives). A side effect is an expected and known effect of a drug that is not the intended therapeutic outcome.

Both allergies and sinus infections can feel miserable. However, these conditions aren't the same thing. Allergies occur as a result of your immune system's reaction to certain allergens, such as pollen, dust, or pet dander. A sinus infection, or sinusitis, occurs when your nasal passages get infected.

Rhinitis is the term for a cold, while sinusitis is a sinus infection. More than 100 different viruses cause a cold, a type of viral infection of the respiratory system. Colds spread when someone who has the virus coughs or sneezes droplets containing the virus into the air.

Key Symptoms of a Cold It can be difficult to identify if you have a cold or flu because these symptoms overlap. It may be helpful to remember that a runny, stuffy nose is a common indicator of a cold, along with scratchy throat, sneezing, watery eyes, and a mild fever (below 102 F).

Newer antihistamines, such as Claritin (generic: loratadine) and Zyrtec (generic: cetirizine), work better for allergies but not as well for colds.

Symptoms. Initially, the flu may seem like a common cold with a runny nose, sneezing and sore throat. But colds usually develop slowly, whereas the flu tends to come on suddenly. And although a cold can be a nuisance, you usually feel much worse with the flu.

Common Drug Side Effects Telling the difference can be hard, because drug sensitivities may trigger symptoms similar to an allergic reaction. But unlike allergies, side effects don't involve the immune system.

Getting chilly or wet doesn't cause you to get sick. But there are things that make you prone to come down with a cold. For example, you're more likely to catch one if you're extremely tired, under emotional distress, or have allergies with nose and throat symptoms.

Runny nose and sneezing are common symptoms of both colds and allergies. But you can often tell the difference by looking at the color and texture of your mucus. If you have allergies, your mucus will typically be clear, thin and watery.

Intolerances, on the other hand, refer to a difficulty digesting certain kinds of food — the reaction can be unpleasant, but it's not going to kill you. So lactose intolerance and a dairy allergy are two separate things.
