14 Signs of Sever’s Disease

2. Swelling in the Heels

You may notice swelling at the back or bottom of your child’s heel. This swelling often appears where the Achilles tendon attaches to the heel bone, making the area can look slightly puffy compared to the other foot. In some cases, both heels swell, especially if your child stays active during a growth spurt.

Swelling happens because the tendon pulls on a soft growth area in your child’s heel. Repeated stress from running and jumping can irritate this spot and lead to fluid buildup. You might also notice warmth around the swollen area. The skin may look normal, or it may appear mildly red after your child plays sports or goes on long walks.

Puffiness at the back of the heel, tenderness when you press or squeeze the sides, mild warmth after activity, and increased swelling by the end of the day are common signs. If you press on the sides of your child’s heel and they feel pain along with swelling, this can point to Sever’s disease. Tight calf muscles can add more pull on the heel, which can make the swelling more noticeable.

3. Redness

You may notice redness at the back of your child’s heel. This redness often appears right over the area where the Achilles tendon attaches to the heel bone. It can look mild at first and become more visible after sports or long periods of walking. Redness usually happens because the growth plate in the heel becomes irritated. Repeated running and jumping increase blood flow to the area.

This can make the skin look pink or red, especially after activity. In many cases, the redness stays in one heel. It may affect both heels, but it often feels worse on one side. The skin can look slightly swollen along with the color change. You might see more redness when your child wears flat or tight shoes. Shoes that rub against the back of the heel can add friction.

4. Tenderness and Tightness

Your child may feel soreness when you press on the back of their heel. This tenderness often sits right where the Achilles tendon attaches to the heel bone. Even light touch can cause discomfort during a flare-up. The pain may increase after sports or long periods of standing.

Running and jumping can make the area more sensitive. When you squeeze the sides of the heel, you might notice sharp or aching pain. Tightness in calf muscles is also common, shiff calves can pull harder on the heel. This extra tension adds stress to the growth plate and raises their discomfort.

Tight muscles can make it harder for them to flex their feet. Your child may struggle to lift their toes toward their shin. This reduced motion can affect how they walk or run. If the tightness continues, your child’s heel may stay sore even after rest.

5. Exercise-Induced Pain

Your child often feels heel pain during or after physical activity, especially with running, jumping, and fast changes in direction can trigger it. Sports like soccer, basketball, and gymnastics place repeated stress on their heel. The pain usually starts at the back or bottom of their heel. It may feel sharp when they push off the ground.

After they stop playing, the pain can turn into a dull ache. High-impact movement makes symptoms worse because their calf muscles pull on the growth area of the heel bone. During growth spurts, their bones grow faster than their muscles and tendons, which increases strain when they exercise.

Flat or unsupportive shoes can increase discomfort, and barefoot activity on hard surfaces may also trigger pain. In many cases, they can still move their ankle normally. However, repeated impact keeps irritating the sensitive growth area in their heel, which leads to ongoing exercise-related pain.

6. Difficulty Walking

You may notice that walking feels harder than usual for your child. Heel pain can make them slow down or change the way they move. Even short distances, like walking through school or around your home, may cause discomfort. Pain often gets worse during or right after activity.

If your child runs or jumps often, their heel may feel sore when they try to walk afterward. This can lead them to take shorter steps or avoid putting full weight on the sore foot. Some children begin to limp and may shift their weight to the other foot to avoid pressure on the painful heel.

Over time, this uneven walking pattern can make their legs feel tired or strained. Your child may also walk on their toes without realizing it. Lifting the heel off the ground reduces pressure, but it changes their normal gait and can make walking look stiff or awkward.

7. Limping and Walking on Toes

You may notice your child starts to limp during or after activity, especially after running or sports. Heel pain makes it hard to place full weight on the back of the foot. When the heel hurts, your child may shift weight to the front of the foot, which can cause walking on toes.

Toe walking helps reduce pressure on the sore growth area at the back of the heel. You might also see stiffness first thing in the morning. The limp can improve with rest but return once activity starts again. Some children try to hide the pain, so changes in walking style may be the first clear sign.

If both heels hurt, your child may walk carefully on both feet. If only one heel hurts, the limp may affect just that side. These changes in walking often link directly to heel pain and tight calf muscles during growth spurts.

8. Treatment

You can manage Sever’s disease with simple steps at home. The main goal is to reduce pain and lower stress on your child’s heel while it heals. Most children improve over time as their growth slows. Start with rest by limiting running and jumping for a few weeks, and switch to low-impact activities like swimming or cycling.

Apply ice to the back of your child’s heel for 10 to 15 minutes after activity, wrapping the ice in a towel to protect their skin. You can do this two to three times a day during painful periods. Have your child wear supportive shoes with good heel cushioning. Avoid flat shoes and walking barefoot for long periods. Heel pads or soft inserts can lift and cushion the heel, which may reduce strain on the growth plate.

Stretch your child’s calf muscles every day. Tight calves pull on the heel bone and increase pain. Simple wall stretches and heel drops can help improve flexibility and lower tension. If pain limits daily activity, a healthcare professional may suggest over-the-counter pain relievers such as nonsteroidal anti-inflammatory drugs.

9. Tendonitis

Tendonitis means your child’s tendon becomes swollen and irritated. A tendon is the strong band of tissue that connects a muscle to a bone. In Sever’s disease, this often affects the Achilles tendon at the back of your child’s heel. When your child’s Achilles tendon gets tight or overworked, it pulls on their heel bone and can cause pain and swelling.

Your child may feel soreness where the tendon attaches to their heel, especially after running or jumping. You might notice stiffness in the back of your child’s ankle in the morning, and the area can feel tender when you press on it.

Walking uphill or pushing off your child’s toes may increase the pain. Tendonitis often develops from repeated stress. Sports that involve running, jumping, or quick stops raise their risk. If your child’s calf muscles are tight, they add more strain to the tendon.

10. Plantar Fasciitis

Plantar fasciitis is another common cause of heel pain. It affects the thick band of tissue on the bottom of your child’s foot that connects their heel bone to their toes, supports their arch, and helps them walk. When this band becomes irritated or swollen, your child may feel sharp pain under their heel.

The pain often feels worse with their first steps in the morning or after they sit for a long time. It may ease as they move, but it can return after long periods of standing or walking. Plantar fasciitis is more common in adults, but active teens can also develop it. Running, wearing flat or worn-out shoes, and having very high or very flat arches can increase your child’s risk.

Unlike Sever’s disease, this condition does not involve the growth plate in the heel. You may notice tenderness along the bottom of your child’s foot instead of the back of the heel. Pressing on the center of the heel from underneath often triggers pain. The pain usually stays in one spot rather than spreading around the heel.

11. Heel Bursitis

Heel bursitis causes swelling of a small fluid-filled sac near the back of your child’s heel bone, called a bursa. This bursa reduces friction between the heel bone and the Achilles tendon, but irritation leads to pain and tenderness similar to Sever’s disease.

Children with Sever’s disease often experience added strain on the heel, especially if their calf muscles are tight. You might notice swelling at the back of your child’s heel. The area can feel warm or sore when you press on it. Pain often gets worse when they walk, run, or wear tight shoes that rub against the heel.

Common signs of heel bursitis include pain at the back of the heel and swelling or puffiness near the Achilles tendon. Tenderness when you squeeze or press the area and stiffness after rest are also common. You may also notice that your child limps or avoids putting full weight on their heel.

12. Withdrawal From Social Sports Activities

Your child may start to pull away from team sports or group play because heel pain from Sever’s disease often gets worse with running and jumping. To avoid pain, your child may skip practice or ask to sit out during games. This change can happen slowly, starting with leaving practice early and eventually stopping attendance entirely.

You might also see mood changes. Your child may feel frustrated or left out when friends continue to play. Sports often play a big role in social life at this age, so stepping back can affect friendships. Watch for patterns. If your child only avoids high-impact activities like soccer, basketball, or gymnastics, heel pain may be the cause. Low-impact activities such as swimming or cycling may feel easier and more comfortable.

13. Pain When Standing

You may notice that your child feels heel pain as soon as they stand up. The pain often starts at the back or bottom of their heel and can feel sharp at first, then turn into a dull ache. Your child’s Achilles tendon pulls on the growth plate in their heel.

When they stand, their body weight presses down on this area, which causes pain if the growth plate is irritated. You might notice the pain more after your child sits for a long time. For example, standing up after class or getting out of bed can trigger discomfort. The first few steps may feel stiff and sore.

Common patterns include pain that improves slightly after your child moves around and pain that returns after long periods on their feet. Discomfort may occur in one heel or both. Hard floors can make the pain worse, and standing barefoot may also increase pressure on the heel.

14. Risk Factors

Sever’s disease risk increases during growth spurts, typically between ages 8 to 12 in girls and 10 to 14 in boys. Rapid bone growth can outpace muscle and tendon development, which creates tightness and stress on the heel. High-impact sports and inadequate rest further raise your child’s risk.

Activities that involve repeated running and jumping, such as soccer, basketball, football, track, and gymnastics, put steady strain on your child’s heel. The calf muscle repeatedly pulls through the Achilles tendon and can irritate the growth plate. Playing sports year-round without enough rest increases pressure on your child’s heels.

Heavy training schedules and wearing flat or poorly cushioned shoes reduce shock absorption and can worsen symptoms. Other factors can add to the strain on your child’s heel. Tight calf muscles and tight plantar fascia on the bottom of the foot are common contributors. Flat feet or poor foot alignment can also increase stress, while low vitamin D levels and leg length differences may further raise the risk.
