Allergies
Sneezing, itchy eyes, rashes and wheeze can all be allergy, but guessing the trigger rarely works. Dr. James maps your symptoms to likely causes and only tests when the answer will change what you do.
Who should see an internist about this
- Repeated sneezing, itchy eyes or a blocked nose that comes in a pattern.
- Hives, itching or rashes that keep returning.
- Suspected food, medicine or insect allergy.
- A chronic cough or wheeze that may be allergy-driven.
- You had a severe reaction before and want a clear plan.
What happens at your visit
The history does most of the work: what appears, when, how fast, and what makes it better or worse. Dr. James examines your nose, throat, skin and chest, and looks for patterns like seasonal flares, home versus work differences, and links to foods or medicines.
Testing is suggested only when it changes management: allergy blood tests or a referral for skin testing when the trigger stays unclear, and an action plan if you have had severe reactions.
How to prepare
- Keep a short diary of symptoms: what you ate, where you were, what touched your skin.
- Bring photos of rashes or swelling taken when they appeared.
- Bring all medicines and supplements, including eye drops and nasal sprays.
After your visit
You leave with the most likely trigger identified, an avoidance plan that is actually doable, and symptom treatment suited to you. If a severe allergy is suspected, an emergency action plan is written out clearly for you and your family.
When to get help straight away
Anaphylaxis is a medical emergency: swelling of the lips, tongue or throat, difficulty breathing or swallowing, widespread hives with dizziness, vomiting or collapse. Go to the nearest emergency department immediately. If you have been prescribed an adrenaline injector, use it first and still go.
Common questions
What is the difference between allergy and intolerance?
An allergy involves the immune system and can cause sneezing, hives, swelling, wheeze or, rarely, severe reactions. An intolerance, like lactose intolerance, causes gut symptoms without immune involvement. The history usually tells them apart before any test.
Do I need allergy testing?
Only if the result will change what you do. If your story already points clearly at a trigger like dust or a pet, avoiding it is the test. Blood or skin tests help when the trigger is unclear or when symptoms continue despite avoidance.
Can adults suddenly develop allergies?
Yes. Adult-onset allergies to foods, medicines and environmental triggers happen. Moving house, a new pet, new cosmetics or a medicine can reveal a new sensitivity. The timing pattern usually gives it away.
Are antihistamines safe to take daily?
Modern non-drowsy antihistamines are designed for regular use and are safe for most adults. Older sedating ones should not be used before driving. If you need them every day for months, a review is worthwhile to check the cause is understood.
Can allergies cause a chronic cough?
Yes. Nasal allergy often causes post-nasal drip, mucus trickling down the throat, which triggers a persistent cough and throat clearing. Treating the nose usually settles the cough without any cough medicine.
