What is Swimmer’s Ear?

Swimmer’s ear, medically known as otitis externa, is an infection of the ear canal—the passage between your eardrum and the outside of your ear. Most cases are caused by bacteria, though fungi can also be responsible.

The infection often develops when moisture becomes trapped in the ear canal, softening protective earwax and creating an environment where germs can thrive. Disrupting the natural protective layer of earwax—such as by using cotton swabs or other objects—can also make the ear canal more susceptible to infection.

Children and individuals who spend significant time in water are particularly prone to developing swimmer’s ear.

Swimmer’s Ear vs. Ear Infection

A common point of confusion is the difference between swimmer’s ear (otitis externa) and typical middle-ear infections (otitis media).

• Otitis externa (swimmer’s ear): Infection of the ear canal
• Otitis media: Infection behind the eardrum, in the middle ear

Both conditions require medical attention, as bacterial infections can worsen if left untreated.

Signs and Symptoms of Swimmer’s Ear

Swimmer’s ear is often easy to identify due to its hallmark list of symptoms, which include:

• Ear pain
• Swelling of the ear canal
• Feeling of fullness in the ear
• Itching in the ear canal
• Drainage from the ear
• Mild discomfort worsened by pulling on the outer ear or pressing on the tragus (the small bump in front of the ear canal)

Advanced infections may present with:

• Severe pain radiating to the head or neck
• Fever
• Blockage of the ear canal
• Swollen lymph nodes in the neck

These symptoms should never be ignored, as prompt treatment is necessary to prevent complications.

---

Diagnosing and Treating Swimmer’s Ear

Persistent or worsening ear pain is a signal to seek care. Diagnosis usually begins with a physical exam of the ear, and the ear canal may be cleaned if needed.

Treatment may include:

• Prescription ear drops containing antibiotics or steroids
• Oral antibiotics for more severe infections

When treated promptly, most cases of swimmer’s ear resolve without complications.

What is Sun Poisoning?

“Sun poisoning” is a non-medical term commonly used to describe a severe sunburn. While most sunburns are uncomfortable, sun poisoning can be much more serious—often causing extensive redness, swelling, blistering, and systemic symptoms. Repeated or severe sun exposure can also contribute to long-term skin damage, including premature aging and an increased risk of skin cancer.

Sun poisoning typically occurs after prolonged sun exposure without adequate protection, especially during peak UV hours.

Several factors can increase a person’s risk of developing severe sunburn, including:

• Fair or sensitive skin
• Very young or older age
• Exposure to reflected sunlight (such as from water, sand, or snow)
• Certain medications that increase sun sensitivity, including some antibiotics, isotretinoin (Accutane), and birth control pills

---

What are the Symptoms of Sun Poisoning?

Symptoms of sun poisoning can vary depending on the severity of the burn. In some cases, symptoms may not appear until 6–10 hours after sun exposure, often beginning with redness, swelling, and itching of the affected skin.

More severe cases may also involve heat exhaustion or heat stroke, which can raise body temperature and affect overall health. Symptoms that may indicate sun poisoning or a medical emergency include:

• Fever or chills
• Headache
• Confusion or disorientation
• Nausea or vomiting
• Blurred vision
• Fainting or dizziness

Anyone experiencing these symptoms should seek medical care as soon as possible.

---

Diagnosing and Treating Sun Poisoning

Treatment for sun poisoning depends on the severity of symptoms. A physical exam and discussion of symptoms are typically enough to determine the appropriate course of care.

For mild sunburns, treatment may include:

• Drinking plenty of fluids
• Cool compresses or cool-water baths
• Soothing or medicated topical creams

More severe cases of sun poisoning may require:

• Pain-relieving medications
• Oral steroids to reduce inflammation
• IV fluids if dehydration or heat-related illness is present

Prompt treatment can help reduce discomfort and prevent complications.

---

What Can You Do to Prevent Sun Poisoning?

Excessive sun exposure can cause lasting skin damage, but sun poisoning is highly preventable with simple precautions. To protect your skin:

• Wear protective clothing or a wide-brimmed hat when spending extended time outdoors
• Apply sunscreen daily—even on cloudy days—with SPF 15 or higher (higher SPF offers more protection)
• Reapply sunscreen regularly, especially after swimming or sweating
• Avoid direct sun exposure between 10 a.m. and 3 p.m., when UV rays are strongest
• Take frequent shade breaks
• Stay well hydrated

What is Dehydration?

Dehydration occurs when the body doesn’t have enough fluids to function properly. We lose water every day through normal activities such as sweating, breathing, talking, and even sleeping. When that lost fluid isn’t replaced, dehydration develops.

Mild dehydration can cause discomfort and fatigue, but severe dehydration can be dangerous—and in extreme cases, life-threatening.

Common causes of dehydration include:

• Not drinking enough water
• Excessive sweating
• Heat exhaustion
• Diarrhea
• Vomiting
• Intense physical activity
• Certain medical conditions, including diabetes

People at higher risk for dehydration include athletes, older adults, young children, and individuals living or exercising at higher altitudes, where fluid loss can occur more rapidly.

---

What are the Signs and Symptoms of Dehydration?

Early symptoms of dehydration are often subtle and may include increased thirst, decreased urination, and darker-colored urine. As dehydration worsens, additional symptoms may appear, such as:

• Fatigue
• Headache
• Dry mouth
• Weakness
• Muscle cramps or aches
• Dizziness or lightheadedness
• Nausea
• Dry skin

In severe cases, dehydration can cause fever, confusion, delirium, or loss of consciousness. These symptoms should be treated as a medical emergency, and care should be sought immediately.

---

Diagnosing and Treating Dehydration

Dehydration is typically diagnosed through a physical exam and discussion of symptoms. Mild to moderate dehydration can often be treated with oral fluids and rest.

In more severe cases, or when symptoms do not improve, IV fluids may be necessary to restore hydration levels safely and quickly. Prompt treatment can help prevent complications such as heat exhaustion or heatstroke.

Four Tips for Preventing Dehydration

While dehydration can be serious, it is often preventable. Follow these tips to stay hydrated, especially during hot weather and outdoor activities:

1. Drink plenty of water: Water is the most effective way to stay hydrated and should be consumed regularly—even before thirst sets in.
2. Stop activity if symptoms appear: Pushing through dehydration can worsen symptoms and increase the risk of heat-related illness.
3. Rest in a cool environment: Move to shade or an air-conditioned space to help regulate body temperature.
4. Cool down the body: Taking a cool shower or bath can help lower body temperature while you work to rehydrate.

What is Poison Ivy and How Can It Be Identified?

Poison ivy is a toxic plant that grows throughout much of the United States and is especially common in wooded areas, backyards, and even urban environments across New England. It typically grows low to the ground and features three distinct leaves, which can change color with the seasons. Depending on conditions, poison ivy may appear as a ground cover, shrub, or climbing vine, and it may produce small flowers or berries.

When people refer to “getting poison ivy,” they are usually describing contact dermatitis, a skin rash caused by exposure to urushiol—an oily resin found in the plant. Most people are allergic to urushiol. Simply touching the plant or coming into contact with clothing, tools, or pets that have touched poison ivy can trigger a rash.

Burning poison ivy is especially dangerous. Inhaling smoke that contains urushiol can cause severe irritation to the lungs and airways and may require emergency medical care.

---

What are the Signs and Symptoms of Poison Ivy?

Symptoms of poison ivy exposure vary depending on the amount of contact and individual sensitivity. Common signs include:

• Red rash, often appearing in lines or streaks where the plant touched the skin

• Redness and swelling

• Blistering

• Intense itching

If poison ivy smoke is inhaled, symptoms may include difficulty breathing, coughing, or throat irritation. These symptoms can signal a medical emergency and should be evaluated immediately.

---

Diagnosing and Treating Poison Ivy

Poison ivy rashes are common and typically easy for urgent care providers to identify with a visual exam. Mild cases are often treated with supportive care, including:

• Calamine lotion
• Cool compresses or cool-water baths
• Oatmeal-based products
• Over-the-counter antihistamines or anti-itch medications

For rashes that are widespread, severe, or involve significant blistering, a provider may prescribe oral or topical corticosteroids to reduce inflammation. Antibiotics are only prescribed if there are signs of a secondary skin infection caused by scratching.

---

Tips for Preventing Exposure to Poison Ivy

The best way to prevent poison ivy rash is to avoid contact with the plant—but that’s not always easy. These steps can help reduce your risk:

1. Learn to identify poison ivy: Look for three pointed leaves that may have smooth or slightly notched edges. Leaves are typically green in summer and can turn red or yellow in the fall.
2. Wear protective clothing: Long sleeves, long pants, and gloves can help limit skin exposure when spending time outdoors.
3. Wash clothing promptly: Urushiol can linger on fabric. Wash clothing, shoes, and gear after outdoor activities if exposure is possible.
4. Don’t scratch! If you do end up with a poison ivy rash, avoid scratching it even if it’s very itchy, as scratching can lead to infection.
