A pulled calf muscle is a really common sporting injury that can cause long-term problems if not effectively managed.
Other common terms for this injury include a calf muscle strain, calf tear and torn calf muscle.
Essentially, what all these terms refer to is one of the calf muscles being pulled beyond its normal elastic limit, overstretching it and damaging some or all of muscle fibers.
With a calf strain there is usually sudden, intense pain, the area may be tender to touch with swelling and bruising and walking is often difficult.
There are three
grades of calf muscle strain, depending on how much of the muscle is damaged.
Here we will look at what muscles make up the calf complex, how they are injured, the common symptoms experienced, what the best treatment options are and how to prevent yourself from suffering from a pulled calf muscle.
The calf is made up of two muscles, gastrocnemius and soleus. They work together to pull the foot downwards into plantarflexion e.g. pointing your toes or lifting your heel up off the floor.
The deep soleus muscle arises from just below
the knee joint. The gastrocnemius muscle sits over the top of the soleus muscle
and arises from just above the knee.
Both muscles join together around the mid-calf level to form the Achilles tendon which attaches the calf to the foot at the back of the heel.
The calf muscles play an important role when the foot is pushing off the ground when walking, running and jumping, and they help to stabilise the ankle.
A pulled calf muscle usually happens suddenly due to injury, but can develop gradually from overuse. A calf muscle strain most commonly affects the larger, more superficial gastrocnemius muscle but can affect the soleus muscle as well.
Acute calf muscle strains occur when the muscle is suddenly overstretched, usually when changing direction or accelerating e.g. sprinting or jumping.
Athletes participating in sports such as tennis, basketball, football, soccer or track events often suffer from calf muscle tears due to the sudden bursts of speed required when moving from a stationary position.
Calf muscle strains can also developed due to repetitive overuse of
gastrocnemius and soleus, usually with running and jumping, especially if the muscles
are weak or tight. A calf strain is the most common cause of calf pain in runners.
There are three grades of calf muscle strain, depending on how much of the muscle is damaged.
The location of pain will depend on where the calf tear is.
Typical symptoms for each grade of pulled calf muscle include:
With a grade 1 calf strain, only a few of the muscle fibres are damaged, up to approximately 10%.
Mild pain may be felt at the time of injury or may not develop until after activity has stopped. The calf may feel tight and painful to move and it may be accompanied by cramp.
Symptoms from a grade 1 pulled calf muscle usually last from a few days to a couple of weeks
With grade 2 muscle tears, more of the muscle fibres are damaged, between 10-90%, but the calf muscle is still intact
Grade 2 pulled calf muscle injuries tend to cause a moderate, sharp pain that is usually felt at the time of injury and there may be resultant swelling and bruising in the surrounding area.
The area will be painful when the
calf muscles contract or are stretched and the region is often tender to touch. The affected person will usually walk with a
limp due to pain and weakness. Symptoms of a grade 2 calf tear usually last 4-6 weeks
With a grade 3 there is a large tear where there is complete rupture of the calf muscle i.e. all the fibres are torn, or a complete rupture of one of the heads of gastrocnemius
When suffering from a completely torn calf muscle, pain will be severe and immediate. The person will be unable to walk on the affected leg.
There will be considerate bruising and swelling with a grade 3 calf tear. There may also be a bulge in the back of the calf just above where the rupture has taken place as the muscle tissue pings up into a lump.
Treatment for a pulled calf muscle aims to prevent further injury, aid healing and ensure full recovery to prevent long-term problems. Pulled calf muscle treatment may include:
With the right combination of these treatments, most people make a full recovery for their pulled calf muscle in just a few weeks. But is important to know which of these treatments are right for you and how to do them correctly.
You can find out everything you need to know in the calf muscle tear treatment article.
Recovery from a calf strain will depend on what level calf strain you have experienced and how well you stick to your rehab program.
Whether you have suffered from a pulled calf muscle in the past or not, prevention is better than cure. By ensuring that your muscles are warmed up before commencing exercise, you reduce your risk of suffering from a calf muscle strain.
You also want to make sure you calf muscles are strong and flexible so that they can cope with strain you put them through:

Pulled calf muscle tear treatment should begin as soon as possible and continued until you have regain full strength, flexibility and endurance in the muscle.
Make sure you check out the calf muscle tear treatment guide to find out everything you need to know, such as how heel lift inserts can make a massive difference, when ice does and doesn't help and how to know when it's safe to start stretching.
A pulled calf muscle is the most common cause of calf pain, but there are other, potentially life threatening causes of calf pain. Visit the calf muscle pain section to find out more.
