Can Allergies Cause Sore Throat

Short Answer: Yes — allergies can cause a sore throat. When your body reacts to allergens like pollen, dust, or pet dander, it produces histamines that can lead to postnasal drip, causing throat irritation, scratchiness, and even swelling. If you’ve been wondering “can allergies cause sore throat and loss of voice?” — the answer is yes, especially with prolonged exposure.

 

Why Your Throat Feels Off: A Familiar Complaint at Our Practice

At Manhattan Medical Arts, we see sore throat complaints linked to allergies every single day — especially during peak allergy seasons in Manhattan. As a team practicing primary care and allergy-related conditions, including Dr. Syra Hanif, our board-certified primary care physician, we’ve treated thousands of patients experiencing that tickly, dry, or raw throat that just won’t go away.

“We’ve found that nearly 40–50% of patients who come in with a ‘cold that won’t quit’ are actually dealing with allergy-induced sore throats, not infections.” — Dr. Syra Hanif, MD

 

How Allergies Cause a Sore Throat

When allergens enter your system, your body releases histamines — chemicals that defend against perceived threats. This causes:

• Increased mucus production 
• Swelling in nasal passages 
• Postnasal drip (mucus sliding down the back of the throat) 

That constant drip leads to irritation. This is often how people end up with a scratchy throat, itchy throat, or even red throat from allergies. This can last as long as you’re exposed — which answers the question: “how long does a sore throat from allergies last?” Sometimes, weeks.

Common Allergy Symptoms That Impact Your Throat

• Persistent dry, itchy throat 
• Feeling of needing to clear your throat 
• Mucus buildup from postnasal drip 
• Hoarseness or loss of voice 
• Difficulty swallowing 

These symptoms typically don’t come with fever or body aches — helping you differentiate them from infection.

Can Allergies Make You Lose Your Voice or Cause Swelling?

Yes. Chronic exposure to allergens can lead to swollen throat, inflammation of the vocal cords, and even temporary voice changes. If your symptoms include throat tightness or difficulty breathing — seek immediate care.

 

Our Experience with Allergy-Related Sore Throat in Manhattan

At Manhattan Medical Arts, our providers — led by Dr. Syra Hanif — frequently manage sore throat cases connected to allergies.

Clinical Insight:

We’ve seen seasonal spikes in sore throat visits increase by up to 60% during spring and fall pollen seasons. Most patients were initially misdiagnosed with colds before allergy testing confirmed otherwise.

We use symptom mapping, exposure history, and diagnostic testing to confirm if allergies are the root cause.

 

Allergy Testing: Confirming an Allergy-Linked Sore Throat

Here’s how we test:

• Nasal endoscopy (if needed) 
• Throat and nasal swab to rule out strep or COVID 
• Blood IgE testing or skin prick testing to identify allergens 

These results guide targeted treatment plans.

How Do You Get Rid of a Sore Throat from Allergies?

We recommend a blend of short-term relief strategies and long-term allergy control methods:

• Identify and avoid triggers (pollen, pet dander, dust mites)
• Use air purifiers and clean HVAC filters regularly
• Shower and change clothes after being outside
• Sleep with a humidifier to soothe nighttime throat dryness

For persistent cases, talk with a provider about customized treatment options tailored to your symptoms.

Remedies to Soothe a Sore, Scratchy, or Itchy Throat

• Sip warm liquids (broth, herbal teas)
