Is it allergies or a sinus infection? Knowing how to tell the difference is essential for getting the right treatment—especially in a place like New York City where both conditions are common. Allergies and sinus infections (sinusitis) share similar symptoms such as nasal congestion, pressure, and headaches, but they have different causes and require different treatments.
This blog explains how to distinguish between the two and what to do if your symptoms persist or worsen.

While both conditions inflame the nasal passages, allergies are immune-based, while sinus infections are typically infectious.
Although the symptoms overlap, there are some telltale signs that can help you tell allergies from sinus infections:
If symptoms worsen over time or persist beyond 10 days with facial pressure and fever, it’s likely an infection.
A board-certified allergist will conduct a thorough medical history and may recommend:
Correct diagnosis is essential to avoid using antibiotics when they’re unnecessary or ineffective.
Patients who suffer from recurring sinus infections may benefit from further evaluation to rule out allergies or structural issues.
In some cases, untreated allergies can set the stage for sinus infections. Constant inflammation and mucus buildup create the perfect breeding ground for bacteria. That’s why managing allergies can help prevent sinus problems altogether. Patients who treat their allergies often experience fewer sinus infections and a better quality of life.

According to the latest research, one out of five people suffer from seasonal allergy, i.e., pollen. This happens when your body reacts to an outdoor allergen. Usually, the pollen of insect-pollinated plants, such as grasses, trees, and weeds are the most common causes of this problem. Over-exposure to pollen can lead to many problems. The main issues could be respiratory allergies, including asthma and allergic rhinitis. Let’s have a look at the ways through which you can protect yourself from different outdoor allergens:
You can not suffer from grass pollen all around the year; they come in certain seasons. Rain, temperature, and the times of day are some of the factors that affect the temperature. There are about 1,200 grass species all over North America, which can cause allergies. Some of the major ones are Johnson grass, Bermuda grass, Orchard grass, and Timothy grass, etc.
However, you can follow some of the steps to protect yourself from these. It is recommended to stay early morning indoors between 5, and 10 am. Pollen levels are lower in the evenings. Therefore, it is highly recommended to go for outdoor activities during that time. This way you will be able to save yourself from pollen attacks.
Moreover, you are advised to keep windows and doors of your house closed during the daytime. Pollen won’t be allowed to enter your house from any of the entrances. This will keep your house protected from external enemies. If you feel warm inside the house with closed doors, prefer using an air conditioner. This would make you feel good as well as protect you.
Some of the prolific producers of pollen allergens are a curly dock, ragweed, quarters, lambs, plantain, and sheep sorrel. Plant pollen levels usually take place during the months August and September. The time when there is the most chance of pollen is mid-September. Pollen levels are the highest in dry, hot, and windy mornings.
Moreover, pollen can also make you feel bad when it comes to your clothes. This is the reason why specialists advise not to use a line outside your house, try using a clothes dryer so that pollen does not come on your clothes. When you keep clothes in the open air, it is easiest for pollen to stay on the clothes. When you wear them, you get direct contact with pollen, and you feel sick.
As all the plants have different times to produce pollen, trees usually do this during January and as late as in July. They distribute the highest amount of pollen. Moreover, there are about 100 types of trees that cause allergies. One of the most common allergies from the tree is oak.
It is said to follow similar strategies related to keeping away from pollen. You should follow all the tips discussed above. Most importantly, it is advised not to mow by you, hire someone else for the job. However, if you do, remember to wear a mask.
