As your primary healthcare provider, Dr. Harrison offers expert diagnosis and management for a wide range of common health conditions. Common areas of focus include:
- Mastocytosis: Mastocytosis is a rare condition where too many mast cells, a type of immune cell, build up in your body, causing symptoms like itching, skin rashes, and digestive problems; an allergist/immunologist can help manage these symptoms and complications.
- Rash: An allergist/immunologist can help determine if your rash is related to allergies, such as contact dermatitis, or another underlying condition and provide appropriate treatment.
- Pollen Allergy: Suffering from itchy eyes, a runny nose, and congestion during pollen season? You may have a pollen allergy, and an allergist can help you manage it with testing and treatment options like medication or immunotherapy.
- Asthma: Asthma is a lung condition causing wheezing, coughing, and shortness of breath, and an allergist/immunologist can help you manage your symptoms and prevent attacks.
- Allergic Conjunctivitis: An allergist can help you manage allergic conjunctivitis, a common condition that affects your eyes and causes itching, redness, and watering.
- Animal Allergies: Experiencing symptoms like itchy eyes, runny nose, or skin rash after contact with animals suggests a possible allergy; an allergist can help determine which animals are causing the reaction and develop a personalized management strategy.
- Chronic Sinusitis: An allergist/immunologist can help determine if allergies or immune issues are contributing to your chronic sinusitis and offer effective relief strategies.
- Allergies: Allergies are your immune system mistakenly attacking something that's not actually harmful, resulting in symptoms such as itching, swelling, or difficulty breathing; allergists diagnose these reactions and offer ways to manage them.
- Bronchitis: Bronchitis is an inflammation of the bronchial tubes, and while an allergist/immunologist might not be the primary care provider for bronchitis, they can help manage related allergies or asthma that may worsen the condition.
- Eczema and Contact Dermatitis: Eczema is chronic, and contact dermatitis is triggered by contact with an irritant or allergen; an allergist helps you manage symptoms and avoid future reactions.
- Eating Disorders: An eating disorder is a serious mental health problem involving extreme eating behaviors that can harm your body; an allergist/immunologist might help manage any related food allergies that are present.
- Angioedema: Angioedema is a type of allergic reaction causing significant swelling; an allergist/immunologist can diagnose this condition and prescribe appropriate treatment to prevent future occurrences.
This list represents some of the common conditions treated. An accurate diagnosis and a personalized care plan can only be developed through a direct consultation with a qualified medical professional.
To provide comprehensive and patient-centered care, Dr. Harrison offers a range of services designed to diagnose, manage, and treat various health concerns:
- Allergy Skin Testing: Allergy skin testing helps your doctor determine the specific allergens causing your symptoms such as sneezing, rash or itching, enabling tailored treatment.
- Drug or Food Challenge: During a food or drug challenge, you'll be carefully observed as you consume small amounts of the suspected allergen to see if it causes any adverse reaction, helping confirm or rule out an allergy.
- Aeroallergen Hyposensitization Therapy: Aeroallergen hyposensitization therapy, or allergy shots, helps reduce allergy symptoms by gradually exposing you to small amounts of what you're allergic to, building up your tolerance over time.
- Food Desensitization Therapy: Food desensitization therapy involves a carefully controlled process where you're exposed to increasing amounts of an allergen to build tolerance.
- Honeybee Desensitization Therapy: For those with serious bee sting allergies, this therapy uses small amounts of bee venom injected over time to decrease the risk of a life-threatening allergic reaction.
- Allergy Treatment: If you suffer from allergies, treatment can involve medication, immunotherapy, or lifestyle changes to manage symptoms.
- Patch Testing: This test involves placing small amounts of potential allergens on your skin to see if you react, helping pinpoint the source of your rash or irritation.
- Desensitization: Desensitization is a type of treatment that gradually reduces your body's allergic reaction to a specific substance.
- Radioallergosorbent Test: A radioallergosorbent test (RAST) is a blood test that helps identify what substances you're allergic to, like pollen or certain foods.
- Food Challenge: A food challenge is a supervised test where you eat small amounts of a food you suspect you're allergic to, to see if you react.
- Allergy Shots: Allergy shots, or immunotherapy, are a series of injections designed to reduce your allergic reactions over time.
- Drug Allergy Testing: Drug allergy testing helps your doctor safely manage your medications and prevent future allergic reactions.

Here are answers to some common questions about receiving Allergy & Immunology care with Dr. Harrison:
- What is the difference between an allergy and a food intolerance?
- Dr. Harrison can differentiate between allergies and food intolerances. An allergy is a life-threatening immune response, while an intolerance typically causes digestive discomfort. Testing can confirm a true allergy.
- Should I stop taking my allergy medication before my appointment for testing?
- For accurate skin testing, please stop taking antihistamines like Zyrtec, Claritin, or Allegra several days before your appointment. Please call our office to discuss which medications to hold and for how long.
- Can a persistent cough be a sign of asthma?
- Yes. A chronic cough, especially one worse at night, with exercise, or during a cold, can be a primary symptom of cough-variant asthma. Dr. Harrison can perform breathing tests (spirometry) to determine if asthma is the cause of the cough.
- How do allergy shots (immunotherapy) work?
- Dr. Harrison's allergy shots, or immunotherapy, are a long-term treatment that gradually introduces increasing amounts of the allergen to your body. This helps train your immune system to tolerate the allergen, reducing your allergic reactions over time.
- Do you treat immune deficiencies?
- Yes, Dr. Harrison specializes in diagnosing and managing primary immunodeficiency disorders (PIDD). If you or a loved one experiences frequent, severe, or unusual infections, he can conduct specialized testing and manage treatments like immunoglobulin therapy.
- My child has a food allergy. What are the chances they will outgrow it?
- Many children outgrow allergies to milk, eggs, soy, and wheat, but allergies to peanuts, tree nuts, fish, and shellfish are often lifelong. Dr. Harrison can monitor your child's condition with testing and may perform a supervised oral food challenge when appropriate.
- What does an allergy skin test feel like? Does it hurt?
- Dr. Harrison's allergy skin tests involve a series of small pricks on the skin, typically the back or arm. While the pricks themselves are generally not painful, a positive reaction may cause a small, itchy bump, similar to a mosquito bite. This reaction helps identify the specific allergen.
- What is patch testing used for?
- Dr. Harrison performs patch testing to identify the causes of delayed allergic reactions, like contact dermatitis, which differ from the immediate reactions detected by skin prick testing. Common triggers identified through patch testing include nickel in jewelry, fragrances, and preservatives in lotions. The test involves placing small patches containing suspected allergens on the patient's back for 48 hours.
