Achilles tendonitis is inflammation (irritation and swelling) of the Achilles tendon.
The Achilles tendon is a band of tough tissue on the back of the foot. It connects
the heel bone to the calf muscles.
What Are the Signs & Symptoms of Achilles Tendonitis?
Achilles tendonitis causes pain above the heel and in the lower leg, especially
after running or doing other physical activities. The pain often gets worse when exercising
and better with rest.
People with Achilles tendonitis also might have:
stiffness and soreness in the heel, especially in the morning
swelling or hard knots in the Achilles tendon
a creaking or crackling sound when moving the ankle or pressing on the Achilles
weakness in the affected leg
pain when pointing the foot
pain with pressure from shoes
What Causes Achilles Tendonitis?
Achilles tendonitis is usually an overuse injury (when repeated movements injure
part of the body). It also can happen when someone:
suddenly increases their exercise
doesn’t warm up the calf muscles before exercising
exercises in worn out, non-supportive, or poor-fitting shoes or sneakers
does not stretch the Achilles tendon and back of the leg after activity
has a direct blow to the area
Who Gets Achilles Tendonitis?
Achilles tendonitis usually affects people who play sports that put strain on the
heel, such as running, jumping, tennis, basketball, figure skating, skiing, or dancing.
How Is Achilles Tendonitis Diagnosed?
To diagnose Achilles tendonitis, health care providers:
ask about symptoms
do an exam
Occasionally, doctors order imaging tests such as an X-ray or MRI (if they think
the Achilles tendon may be torn).
How Is Achilles Tendonitis Treated?
Treatment for Achilles tendonitis starts with taking a break from the activity
that led to the injury. It’s usually OK to do non-weight bearing exercises such
as swimming, biking, and stretching activities like yoga. If someone with Achilles
tendonitis does not rest, the tendon can become more damaged.
Your health care provider also may recommend:
stretching the Achilles for 30 seconds at a time 3–4 times a day
putting ice or a cold pack on the heel every 1–2 hours for 15 minutes at
a time. (Put a thin towel over the skin to protect it from the cold.)
taping or using athletic wrap around the Achilles tendon and ankle
raising the foot above the level of the heart to help with swelling
taking ibuprofen (Advil, Motrin, or store brand) to help with pain and swelling
strengthening and stretching muscles through physical therapy or an at-home exercise
wearing a walking boot and using crutches to keep the tendon still
using shoe inserts (also called shoe orthotics) from your health care provider
or someone trained in fitting orthotics
applying soft pads to the Achilles if it rubs against a shoe surface or wearing
strengthening the surrounding muscles to take stress off the Achilles and help
support the ankle
Steroid injections in or around the Achilles tendon have been linked to tendon
rupture and aren't recommended.
Rarely, a person might need surgery if the symptoms do not go away after following
the health care provider's recommendations.
What Else Should I Know?
With rest, Achilles tendonitis usually gets better within 6 weeks to a few months.
To lower your risk of Achilles tendonitis again:
Stay in good shape year-round. Drink plenty of water to flush out inflammation,
and eat healthy whole grains, vegetables, and fruits to decrease inflammation.
Increase the intensity and length of your exercise sessions gradually. Experts
recommend just a 10% increase in activity per week. This is especially important if
you've been inactive for a while or you're new to a sport.
Always warm up before you go for a run or play a sport and cool down by stretching
Stretch your legs,
especially your calves, hamstrings, quadriceps, and thigh muscles. After activity,
hold your stretches for 30 seconds and repeat several times a day.
Wear shoes that fit properly and are made for your sport. Replace them before
they become worn out.
Try to run on
softer surfaces, like grass, dirt trails, or synthetic tracks. Hard surfaces like
concrete or asphalt can put extra pressure on the joints. Also avoid running up or
down hills as much as possible.
Do different kinds of exercise, such as yoga,
biking, and swimming. Work different muscle groups to keep yourself in good shape
overall and to prevent overusing
If things don't improve, see your doctor, as it may be a sign that you have a different
