Hives and swelling can be uncomfortable, frustrating, and sometimes frightening. Raised itchy welts, sudden facial swelling, lip swelling, or swelling around the eyes can appear without warning and may come and go quickly. In some cases, hives are short-lived. In others, they return for weeks, months, or longer.
At Steven Schnipper MD, PC, patients receive personalized evaluation and treatment from an experienced board-certified allergist with offices in Murray Hill, NYC and New Rochelle, NY. Dr. Steven Schnipper helps patients understand what may be triggering their hives or swelling and creates a practical care plan to reduce symptoms, manage flare-ups, and identify when urgent treatment may be needed.

What Are Hives?
Hives, also called urticaria, are raised, itchy bumps or welts that can appear anywhere on the skin. They may be red, pink, or skin-colored and often change shape or location. A hive may fade within hours, while new ones can appear elsewhere on the body.
The American College of Allergy, Asthma & Immunology notes that hives affect about 20% of people at some point in their lives. While many cases are temporary, recurring or severe hives should be evaluated by an allergy specialist.
What Is Angioedema?
Angioedema is deeper swelling beneath the skin. It can occur with hives or appear on its own. Angioedema often affects areas such as the lips, eyelids, face, hands, feet, tongue, or throat.
Swelling can feel tight, painful, warm, or uncomfortable. When swelling affects the tongue, throat, or breathing, it may be a medical emergency.
Common Symptoms of Hives and Swelling
Hives and swelling can look different from patient to patient. Some people develop a few small itchy spots, while others experience widespread welts or deeper swelling.
Symptoms May Include:
- Raised itchy welts
- Red, pink, or skin-colored bumps
- Welts that move or change shape
- Burning or stinging skin
- Swelling of the lips, eyelids, face, hands, or feet
- Pressure or tightness in swollen areas
- Symptoms that come and go
- Flare-ups after certain foods, medications, infections, heat, cold, pressure, or stress
Hives can last from minutes to months or even years, depending on the cause and whether the condition is acute or chronic.
When Hives or Swelling May Be an Emergency
Most hives are not life-threatening, but hives and swelling can sometimes be part of a serious allergic reaction called anaphylaxis.
Seek Emergency Medical Care Immediately If You Have:
- Trouble breathing
- Throat tightness
- Tongue swelling
- Dizziness or fainting
- Chest tightness
- Severe abdominal symptoms after a possible allergic exposure
- Rapidly worsening swelling
- Hives with symptoms involving more than one body system
If you have had a severe allergic reaction before, Dr. Schnipper can help you understand your risk and whether you need an emergency action plan.
Acute Hives vs. Chronic Hives
Understanding how long hives have been occurring can help guide diagnosis and treatment.
Acute Hives
Acute hives usually last less than six weeks. They may be triggered by infections, foods, medications, insect stings, or other exposures.
Chronic Hives
Chronic hives last more than six weeks and may appear at least twice a week. Chronic hives are often not caused by a traditional allergy, even when symptoms look allergic. An allergist can help determine whether testing is needed and create a treatment plan to control symptoms.
The American College of Allergy, Asthma & Immunology describes chronic hives as symptoms that appear at least twice weekly and last longer than six weeks.
Common Causes and Triggers of Hives
Hives can be triggered by allergic and non-allergic causes. In many chronic cases, the exact cause is not easy to identify, but treatment can still be effective.
Possible Hives Triggers Include:
- Foods
- Medications
- Insect stings
- Viral or bacterial infections
- Heat
- Cold
- Exercise
- Pressure on the skin
- Sweating
- Alcohol
- Stress
- Latex
- Environmental allergens
- Autoimmune activity
- Unknown internal triggers
Because triggers vary widely, a careful medical history is one of the most important parts of a hives evaluation.
Hives and Swelling Testing in NYC & New Rochelle
Not every patient with hives needs the same testing. Dr. Schnipper evaluates your symptoms, timing, possible triggers, medications, medical history, and recurrence pattern before recommending the next step.
Your Evaluation May Include:
1. Detailed Symptom History
Dr. Schnipper reviews when the hives started, how long individual welts last, whether swelling occurs, what medications you take, and whether symptoms happen after foods, infections, exercise, pressure, heat, cold, or other exposures.
2. Allergy Testing When Appropriate
If your history suggests a possible allergic trigger, allergy testing may help evaluate foods, environmental allergens, medications, or other suspected causes.
3. Medication Review
Certain medications may contribute to hives or swelling. Dr. Schnipper can review prescription medications, over-the-counter products, supplements, and recent medication changes.
4. Chronic Hives Assessment
When hives last longer than six weeks, Dr. Schnipper may evaluate whether the pattern suggests chronic spontaneous urticaria, physical urticaria, autoimmune factors, or another cause.
5. Swelling and Angioedema Review
Swelling without hives may require a different evaluation than hives alone. Dr. Schnipper can assess whether symptoms appear histamine-related, medication-related, hereditary, or connected to another medical issue.
Hives and Swelling Treatment in NYC & New Rochelle
Treatment depends on the type of hives, severity, frequency, swelling pattern, suspected triggers, and whether symptoms are acute or chronic.
Treatment Options May Include:
- Trigger identification and avoidance when possible
- Non-sedating antihistamines
- Adjusting medication timing or dose when medically appropriate
- Short-term treatment for severe flare-ups
- Management plans for chronic urticaria
- Evaluation for allergy-related causes
- Emergency planning for severe allergic reactions
- Follow-up care to monitor response and adjust treatment
A clinical review in Allergy, Asthma & Clinical Immunology describes second-generation, non-sedating H1 antihistamines as the mainstay of therapy for both acute and chronic urticaria. Treatment should always be personalized by a qualified physician.
Can Hives Be Caused by Food Allergies?
Food allergies can cause hives, especially when hives appear soon after eating a specific food. However, chronic hives are often not caused by food allergies. This is why it is important not to remove multiple foods from your diet without a proper evaluation.
Food Allergy May Be More Likely If:
- Hives occur within minutes to two hours after eating
- The same food causes symptoms repeatedly
- Hives occur with lip swelling, throat symptoms, vomiting, wheezing, or dizziness
- Symptoms happen after common allergens such as peanuts, tree nuts, shellfish, fish, milk, egg, wheat, soy, or sesame
Dr. Schnipper can help determine whether food allergy testing is appropriate based on your symptoms.
Can Medications Cause Hives or Swelling?
Yes. Medications can cause hives, swelling, or allergic-type reactions in some patients. Antibiotics, pain relievers, and other medications may be involved. Some blood pressure medications, including ACE inhibitors, can be associated with angioedema.
If you develop swelling or hives after starting a new medication, contact a medical professional. If swelling affects your tongue, throat, or breathing, seek emergency care.

Hives and Swelling FAQ
Why do my hives move around my body?
Hives often appear, fade, and reappear in different areas because they are caused by temporary changes in the skin. A single hive may disappear within hours while new ones develop elsewhere.
Are chronic hives always caused by allergies?
No. Chronic hives are often not caused by a specific food, pet, pollen, or environmental allergy. An allergist can help determine whether testing is needed based on your history.
Can stress cause hives?
Stress may worsen hives or make flare-ups more noticeable in some patients. However, stress is not always the root cause, so persistent hives should be evaluated medically.
What is the difference between hives and angioedema?
Hives affect the surface of the skin and usually appear as itchy welts. Angioedema is deeper swelling beneath the skin and often affects the lips, eyelids, face, hands, feet, or throat.
Should I get allergy testing for hives?
Allergy testing may be useful if your hives happen after a specific food, medication, insect sting, or environmental exposure. Testing is less helpful when hives are chronic and occur without a clear trigger.
Can hives be a sign of anaphylaxis?
Yes. Hives can occur as part of anaphylaxis, especially when combined with breathing trouble, throat tightness, dizziness, vomiting, or widespread swelling. These symptoms require emergency care.
Can hives last for months?
Yes. Chronic hives can last for months or longer. Even when the exact cause is not found, treatment can often reduce itching, welts, and flare-ups.
What should I track before my hives appointment?
Track when hives appear, how long they last, possible foods or medications involved, illness, stress, exercise, heat, cold, pressure, alcohol, and photos of the rash or swelling. This information can help guide your evaluation.
Can swelling happen without hives?
Yes. Angioedema can occur with hives or by itself. Swelling without hives may require a different evaluation, especially if it is recurrent, severe, or affects the lips, tongue, throat, hands, or feet.
When should I see an allergist for hives?
You should see an allergist if hives are recurring, severe, lasting more than six weeks, associated with swelling, linked to foods or medications, or affecting sleep and daily life.
