Leg Pain in Children After Fever: What Parents Need to Know

When a child recovers from a fever, they should start feeling better quickly. But if they begin complaining about leg pain, it can be confusing and concerning for parents. Muscle aches after an illness are often just part of the body’s natural healing process. However, leg pain can sometimes signal a more serious issue that needs medical attention. Understanding the possible causes can help you decide whether it’s a normal post-viral symptom or a reason to contact a doctor.

Common Causes of Leg Pain After Fever in Children

Several conditions can lead to leg pain following a fever. While most are temporary and not cause for concern, some require medical attention.

• Post-viral myositis – A common reason for leg pain after a viral infection in a child, this condition occurs when a virus causes temporary muscle inflammation. It usually affects the calves and can make walking uncomfortable.
• Viral arthritis – Some infections cause joint inflammation, leading to fever and joint pain in kids. The knees, ankles, and hips are most commonly affected.
• Growing pains vs. post-viral leg pain – While growing pains usually happen at night and are not linked to illness, post-viral muscle aches in children can occur at any time after a fever.
• Rheumatic fever and leg pain – Though rare in the U.S., untreated strep throat can lead to rheumatic fever, which causes inflammation in the joints and can result in long-term complications.
• Other infections – Bacterial infections like osteomyelitis (bone infection) or septic arthritis (joint infection) can cause severe leg pain and require urgent medical care.

Recognizing the cause of your child’s leg pain after a fever can help you determine whether it is a passing discomfort or something that needs medical attention.

When to Seek Medical Attention

Most of the time, leg pain after a fever isn’t a big deal and goes away on its own as the body heals. But in some cases, certain symptoms could mean there’s something more serious going on. If the pain doesn’t seem to be improving or comes with other unusual signs, it’s important to pay attention. You should think about calling your child’s doctor if they have:

• Persistent pain lasting more than a few days
• Swelling, redness, or warmth in the legs
• Difficulty walking or refusal to bear weight
• A high fever that returns after initially going away
• Severe pain that worsens instead of improving

These symptoms may indicate an infection or other serious condition requiring quick medical attention. If you notice them, seek professional guidance to determine if the pain is normal or needs treatment.

When should I go to the ER for leg pain?

Emergency care may be necessary if your child experiences any of the following symptoms:

• Sudden, severe leg pain that worsens quickly
• Loss of sensation, numbness, or weakness in the legs
• Difficulty moving their legs or an inability to walk
• Signs of a serious infection, such as a high fever, chills, or worsening redness and swelling

These symptoms could indicate a more serious underlying condition, such as a neurological issue, a deep infection, or a circulatory problem.

How to Treat Leg Pain and Fever in a Child at Home

If your child’s leg pain is not severe, at-home remedies can help relieve discomfort while they recover:

• Rest and hydration – Encourage your child to take it easy and drink plenty of fluids to support their immune system.
• Warm baths – A warm bath can soothe sore muscles and promote relaxation.
• Gentle stretching and massage – Lightly massaging the legs can ease muscle tension and improve circulation.
• Over-the-counter pain relievers – If your child is uncomfortable, acetaminophen or ibuprofen (as directed by their doctor) can help reduce pain and inflammation.

Is Leg Pain After a Fever Normal?

Most of the time, leg pain after a fever is just a short-term reaction to a virus and goes away in a few days. But it’s still important to pay attention if the pain doesn’t improve or comes with other symptoms like swelling or trouble walking. If things seem to be getting worse instead of better, it’s a good idea to talk to a doctor.
