Pain and Swelling in Children: Zarminali Pediatrics

Understanding Pain in Children

Pain is the body's signal that something needs attention. Pain is subjective: It feels different to every person, and children of different ages express it in different ways.

A Note on Pain Thresholds and Tolerance

One child may describe mild soreness as a 9 out of 10, and another may walk on a broke bone without complaint. Neither child is wrong. The goal is not to compare your child to others but to compare your child to themselves. If something seems different from normal, that is worth noting.

Understanding Swelling

Swelling is what happens when extra fluid collects in the tissues. It can be limited to one area with a clear cause, like a bee sting or a sprained ankle, or it can be more widespread.

Swelling Plus Fever: A Combination That Always Gets Our Attention

When fever and swelling occur together, it can indicate an infection or inflammatory reaction that needs prompt treatment.

Understanding When Your Child Needs Care for Pain and Swelling

Knowing when to reach out helps you care for your child confidently. If you are concerned or unsure about pain or swelling, reach out to your Zarminali clinician.

Contact the Clinic for Pain

We want to check your child if:

Your child is under 1 year of age
Pain has no clear cause and does not improve with home care
Pain is waking your child from sleep
Your child is limping for more than 24 hours
Your child is unable to bear weight
You are worried about the pain

Contact the Clinic for Swelling

Tell your clinician right away if your child has:

Any swelling in a child under 1 year old
Swelling without a clear cause
Swelling accompanied by fever
Swelling that is spreading rapidly
Swelling around a joint, especially with stiffness or limping
Swelling after an animal bite
Severe pain or swelling after a fall or injury
Swelling with red streaks on the skin
Eye swollen shut
Generalized swelling

If you cannot reach your clinic and your child has any of the above symptoms, go to urgent care or the ER.

Seek Emergency Care

Call 911 or seek emergency care for:

Swelling of the lips, tongue or throat
Swelling with difficulty breathing
Back pain or injury with numbness in the back or limbs, or back pain with loss of bladder/bowel control

If you are unsure whether your child’s pain or swelling is an emergency, please call to speak with our triage nurses.

Age

A child's ability to communicate pain changes dramatically with age.

Babies can't tell you pain their pain. Any pain or swelling is always worth a call. Look for behavioral cues that suggest a baby might be in pain:

Crying more easily or being more difficult to settle
Persistent crying lasting several hours
Pulling their legs toward their belly while crying
Refusing to feed normally

Toddlers and preschoolers can tell you that something hurts, but they often can’t pinpoint where the pain is coming from or describe it in much detail. They may also exaggerate or minimize pain depending on the situation. A child distracted by play may not mention pain at all until playtime is over. Watch for changes in their behavior, such as

Unwillingness to engage in their normal play or daily activities
Waking in the night from pain
Limping or guarding an area of the body

School-age children and teens can usually tell you where the pain is, what makes it better or worse, and how long it has been going on.

Duration

Pain or swelling that lasts beyond what you would expect for a minor illness or injury deserves attention.

Most localized swelling from a minor injury or bug bite improves within 48 to 72 hours. Pain that has persisted for more than a few days without a clear cause, or swelling that is still worsening after 24 to 48 hours despite home care, is worth a call to our office.

Pattern and Location

These clues help us pinpoint what might be going on:

Location of pain or swelling
If it repeatedly shows up in the same place or different places
When it started and how long it has been going on
If it follows a pattern tied to meals, activity, school, etc.
What makes it better or worse
If it wakes your child from sleep

Underlying Conditions

Children with known medical conditions may experience pain or swelling as part of their underlying diagnosis, or as a sign that something has changed. If your child has a known condition and their pain or swelling seems different than usual, please call us rather than waiting to see how it goes.

Emotional Health

Anxiety, depression, and significant stress can produce physical symptoms. These include recurring stomach pain, headaches, and chest tightness. Pain that is influenced by stress or emotions is still real pain.

If your child's pain follows emotional patterns, it is worth mentioning to their care team. Pain might appear before school, during stressful periods, or alongside changes in mood or behavior. These symptoms deserve the same attention as any other symptom, and addressing the emotional piece often helps resolve the physical one, too.

Supporting Your Child at Home

When pain or mild swelling has a clear, minor cause—a small injury, a bug bite, a sore muscle, or a routine illness—there is a lot you can do at home while your child recovers.

For Minor Pain

Pain Relief Medication. For children 6 months of age or older, ibuprofen (Motrin/Advil) is effective against both pain and swelling. Acetaminophen (Tylenol) treats pain, but not swelling. Always dose by your child's weight and use a measuring syringe or cup, not a kitchen spoon.
Rest and comfort. Let your child rest without forcing strict bed rest. Quiet play, reading, and screen time are all fine. Many children naturally slow down when they do not feel well.
Warmth and massage. For growing pains and muscle aches, a warm bath and gentle massage are effective and reassuring. Daily stretching of the quads, hamstrings, and calf muscles may help prevent leg pains.

For Minor Swelling

RICE for soft-tissue injuries (e.g., sprains). Rest, ice, compress, elevate. Rest the area for 48 hours (keeping weight off of it). Apply ice for 20 minutes at a time (never directly on the skin, always wrapped in a cloth) frequently throughout the day. Use a snug (not tight) wrap or elastic brace for compression. Elevate the injured area above heart level for the first 24 hours when possible. If the limb feels numb, tingly, or turns pale or cold with compression, the wrap is too tight and should be loosened immediately.
Cold compress for bug bites and minor reactions. An ice pack wrapped in a cloth applied for 20 minutes helps reduce swelling and discomfort from bites. Oral antihistamines like diphenhydramine (Benadryl) and cetirizine (Zyrtec) reduce itching and swelling. For bee stings, remove the stinger immediately by scraping across the skin with a plastic card. Do not pinch it, as this releases more venom.
Watch the wound. All wounds should be washed thoroughly with soap and water as soon as possible. Make sure your child is up to date on tetanus vaccination. An animal bite deserves a call to our triage nurses, as it may require a visit for preventative antibiotics or other care. Any wound that causes swelling should be monitored closely. Call us if you notice signs of infection: spreading redness, increasing warmth, stiffness, numbness, pus or other discharge, red streaks, or fever.

Here are some common causes of pain:

Growing pains are common in childhood. They typically affect the lower legs and usually occur at night. Growing pains usually respond to massage, warmth, or a dose of acetaminophen or ibuprofen. True growing pains never cause swelling, redness, limping, or pain that persists throughout the day. If any of those features are present, something else is going on and we want to take a look.
Stomach pain is common in children and has many causes.
Headaches can occur for a variety of reasons.
Chest pain in kids is often musculoskeletal or related to acid reflux. That said, chest pain during exercise deserves to be evaluated promptly. Children with a known heart condition or a family history of sudden cardiac events should be seen promptly for unexplained chest pain, especially chest pain during activity.
Limb pain and limping have many possible causes. Any child who limps for more than 24 hours deserves an evaluation. A new limp with fever needs an urgent evaluation, because it can signal a joint infection that requires immediate treatment.

Common causes of swelling include:

Insect bites and stings can cause dramatic swelling, especially in children ages 1 to 5. Bites near the eye may swell almost completely shut. Non-allergic insect bite swelling typically peaks around 48 hours and can take up to a week to fully resolve.
Swollen lymph nodes are common. You can feel lymph nodes in the neck and groin — that is normal. When a child has an infection such as a viral illness (like a cold), the nearby nodes swell and become tender. That is the immune system doing exactly what it should. Lymph nodes often stay enlarged after the illness, especially in young children. If a lymph node continues to swell, or you are concerned about its appearance, we can do an exam in the clinic to determine whether it is normal or needs treatment.
Skin infections (cellulitis or abscess) cause the skin to look red, feel warm, and swell. These are bacterial infections that need antibiotics (cellulitis) or proper drainage (abscess).
Facial swelling, including eyelids, lips, tongue or generalized face swelling, requires special attention. Call our office right away. If your child is having difficulty breathing with facial swelling, call 911.
Joint swelling in children can be caused by injury, infection, or autoimmune disease, all of which require evaluation and treatment.
Generalized swelling is swelling throughout the body, especially in the feet, abdomen, scrotum, or around the eyes. It is never normal and requires prompt evaluation.
