Allergies & Sinusitis

Posted on May 31 2019

Allergy symptoms appear when the immune system reacts to an allergic substance that has entered the body as though it was an unwelcomed invader. The immune system will produce special antibodies capable of recognizing the same allergic substance if it enters the body at a later time. 

When an allergen reenters the body, the immune system rapidly recognizes it causing a series of reactions. These reactions often involve tissue destruction, blood vessel dilation, and production of many inflammatory substances including histamine. Histamine produces common allergy symptoms, such as: itchy, watery eyes, nasal and sinus congestion, headaches, sneezing, runny nose, scratchy throat, hives, shortness of breath, and more. Other less common symptoms are balance disturbances, skin irritations such as eczema, and even respiratory problems, such as asthma

For some allergy sufferers, symptoms may be seasonal, but for others, it is a year round discomfort. Allergy symptom control is most successful when multiple management approaches are used simultaneously. They may include: minimizing exposure to allergens, desensitization with allergy shots, and medications. 

If used properly, medications, including antihistamines, nasal decongestant sprays, steroid sprays, saline sprays, and cortisone type preparations, can be helpful. Though some can cause drowsiness, some over the counter drugs may be beneficial. 

If you have severe allergy problems and they are beginning to interfere with your everyday living, you will most likely want to make an appointment with an otolaryngologist. An otolaryngologist is the most appropriate person to evaluate allergy problems. He or she will gather a detailed history and complete a thorough exam of the ears, nose, throat, head, and neck. Then, they will offer advice on proper environmental control and evaluate the sinuses to determine if an infection or structural abnormality is contributing to the symptoms. 

In addition, the doctor may advise testing to determine the specific allergen that is causing discomfort and they may refer you for an allergy evaluation by an experienced allergy nurse. In some cases, immunotherapy or allergy shots may be recommended. 

Sinusitis



Acute bacterial sinusitis is an infection of the sinus cavities caused by bacteria. It usually is preceded by a cold, allergy attack, or irritation by environmental pollutants. Unlike a cold or allergy, bacterial sinusitis requires a physician's diagnosis and treatment with an antibiotic to cure the infection and prevent future complications.

Normally, mucus collecting in the sinuses drain into the nasal passages. When you have a cold or allergy flare up, your sinuses become inflamed and are unable to drain. This can lead to congestion and infection. Diagnosis of acute sinusitis is usually based on a physical exam and a discussion of your symptoms. Your doctor may also take x-rays of your sinuses or obtain a sample of your nasal discharge to test for bacteria.

When you have frequent sinusitis, or the infection lasts 3 months or more, it could be chronic sinusitis. Symptoms of chronic sinusitis may be less severe than those of acute; however, left untreated chronic sinusitis can cause damage to the sinuses and cheekbones that can sometimes require surgery to repair.

Functional endoscopic sinus surgery is recommended for certain types of sinus disease. With the endoscope, the surgeon can look directly into the nose, while at the same time, removing any diseased tissue and polyps, and clear the narrow channels between the sinuses.

But, how can you tell if you have symptoms of sinusitis, a cold, or just an allergy? Let's break it down below:

Symptom:

Facial Pressure/Pain: This is most common with sinusitis, although it can sometimes happen with an allergy and cold.

Duration of Illness: With sinusitis, the illness usually lasts over 10-14 days, where it varies with allergies, and is typically under 10 days for a cold.

Nasal Discharge: Sinusitis normally has whitish or green colored nasal discharge. Allergy discharge is clear, thin, and watery, while a cold can be thick, whitish, or thin.

Fever: A fever is sometimes a common symptom of both sinusitis and a cold, but is not a common symptom for allergies.

Headache: Headaches are extremely common for all of these issues. It is a definite symptom of sinusitis and can also occur with allergies and a cold, as well.

Pain in Upper Teeth: This is sometimes a symptom of sinusitis, but not for allergies and a cold.

Bad Breath: Occasionally, with sinusitis, you may notice that you exhibit bad breath. Normally, this is not a common symptom of a cold or allergies.

Coughing: Coughing can be a symptom of all, but is most likely seen with a cold.

Nasal Congestion: Similarly, nasal congestion can be a symptom of all, but is most definite in both a cold and sinusitis.

Sneezing: With allergies and a cold, you are most likely to sneeze and have a runny nose. With sinusitis, you are usually so congested that you cannot sneeze.

Whether you have allergies, sinusitis, or a cold, it's always best to be medically evaluated, therefore you have a better knowledge of what treatment or medication would be best for you. Be sure to contact your doctor or other qualified health care professional before taking any medication, supplements, or starting a new health regimen.
