Sneezing, wheezing, and trouble breathing are all symptoms of allergy and sinus problems that probably affect you or someone in your family. Allergy treatment from acute to chronic sinus infections and mild to severe allergic reactions, our skillful team of doctors will be prepared to treat you in Frisco or South Fort Worth, TX at iCare ER & Urgent Care. We will be able to recommend whether you should be treated in the urgent care center or the emergency room, depending on the severity and health risk of your sinus infection or allergic reaction.

Allergies come in many different forms and can cause a variety of reactions, from mild seasonal allergies to severe allergic reactions, known as anaphylaxis. Most immune systems can destroy foreign substances and differentiate between harmful and harmless. Those with allergies, however, have immune systems that overreact to foreign substances, sometimes in extreme ways. Such allergies are listed below:


Seasonal allergies are often caused by pollen, dust, oak, or grass and occur at any time of year.


People can experience a range of reactions to food when they have an allergy. Reactions can be an uncomfortable sensation in the stomach to an immune response that shuts down an airway. The most common food allergies are allergies to shellfish and fish, eggs, milk, wheat, soy, nuts, and sulfites.


Many patients are allergic to the dander of animals (dogs or cats), which can cause a significant reaction on the skin, in the lungs, and in the eyes.


We see patients with critical reactions to bites or stings by bees, wasps, hornets, and fire ants. Allergies to insect stings or bites can cause a local reaction (like extreme swelling) to causing the airway to close and constrict breathing.


Exposure to certain perfumes, creams, cleaning agents, detergents, shampoos, and more can cause mild to severe allergic reactions to the chemicals in the product.


Sinusitis or a sinus infection is a painful inflammation of the air-filled cavities within the face. Caused by either bacteria or fungi, the infection blocks the flow of mucus to the back of the throat through the sinuses, causing swelling and pain. A sinus infection lasting 3 – 8 weeks is considered acute, while symptoms that last longer than 8 weeks are considered a chronic sinus infection.

If you think that you may have a sinus infection, you should come into iCare ER & Urgent Care so that our physicians can help you with the following symptoms:

  • Headaches
  • Tenderness of the face
  • Coughing
  • Fever
  • Fatigue
  • Redness
  • Runny nose
  • Nasal stuffiness or congestion
  • Discolored nasal discharge
  • Pain in the teeth and gums
  • Bad breath

Most often, sinusitis caused by bacteria is treated with antibiotics, but our physicians may also prescribe other remedies such as nasal decongestant sprays, antihistamines, topical nasal corticosteroids, antifungal agents, or nasal saline washes.


If you were given a prescription for a new medication you have never taken before, it is possible for you to have an allergic reaction. The most common medication allergy is penicillin, and a severe reaction can be life-threatening. iCare will see patients with this type of medication reaction.
