Pain in Back of Leg behind KNEE

The knee is one of the largest joint of the body that bears almost all of the body weight. The knee is made up of the ligaments, bones, muscles, and tendons. Not only it holds up body weight but it also works mainly when you decide to run, walk, skip or jump. Knee injuries are so common and if you understand how knee and its parts work then it will be easy to identify the cause of knee pain. Pain in the back of the leg behind the knee is one of the most common injuries.

The knee is a complicated and mostly used joint. It has a lot of moving parts so things can go wrong easily. Sometimes small problems can lead to serious injuries if they’re not treated on time and properly. Pain in the back of the leg behind is most common in athletes, young individuals, senior citizens and the people who commonly work while using their joints mostly.


Different Causes of Pain in the Back of Leg

There are so many issues that can cause pain in the back of the leg behind the knee. Baker’s cyst, leg cramps, ACL, PCL, popliteal vein thrombosis, calf strain, arthritis and many more are discussed in my previous articles. In this article, we’re going to discuss some problems that lead to pain in the back of the leg behind the knee. You’ll find out about the symptoms and treatment along with the causes.

Deep Vein Thrombosis (DVT)

Deep vein thrombosis means clotting of the blood in the deep veins of the legs. It commonly occurs in the large veins that run through the muscles of the calf and thigh. It can develop under certain medical conditions. It can also happen if you have surgery or an accident. Or when you are confined to a bed or you don’t move for a long time. If not treated on time DVT may lead to serious complication such as pulmonary embolism.


DVT can cause swelling and pain in front and back of your legs. Sometimes it can occur without any symptom. Some people with DVT feel pain while standing. Nevertheless, you may feel swelling in the affected area. Fatigue or prominently visible surface veins in the affected leg is a common symptom as well. Red and warm to touch skin also represents DVT. It can become more serious if the blood clot breaks loose into the bloodstream.

Risk factors can include being older, overweight and heart failure. Sedentary lifestyle, smoking and birth control pills can increase blood stability to clot blood in the veins.


To prevent DVT, don’t sit with bent legs for too long and stretch them often if you’re sitting for long. Treatment is aimed to prevent the blood clot from getting bigger. DVT is most commonly treated with anticoagulants aka blood thinners. These injectable medicines can be given an injection or as a shot under the skin. Moreover, you can treat it with filter insertion as well. Compression stockings can help prevent swelling and pain in the back of the legs. They’re worn on legs from feet to the level of knees.

Gastrocnemius Tendonitis (Calf Strain)

The calf is made of three major muscles the medial and lateral gastrocnemius and soleus muscle. These muscles are located on the back of your leg behind the knee and help you bend your knee and point your toes. The most commonly injured muscle when a calf strain happens is the medial gastrocnemius muscle. When calf strain happens it is important to determine whether the gastrocnemius muscle is injured or the soleus muscle. So that appropriate treatment can be given to prevent a recurrence.


Calf strain happens when your internal muscles are overstretched from exercise. Most commonly athletes and runners have this type of injury. A sudden movement can stress the calf muscle in sports like tennis, soccer, baseball, and even simple running. It can also occur from a sudden explosive change of direction. Wearing high heels on a regular basis increase the risk of a torn calf muscle. However, a calf strain can happen suddenly (acute injury) or over time (overuse injury).


Symptoms of a calf strain depend on the severity of the injury. A mild strain may cause aching in the back of the leg behind the knee during and after exercise. A severe pull in your calf muscle can leave you uncomfortable with sharp pain and feelings. Moreover, a feeling of tightness may feel behind the leg during workout or exercise. However, you can still walk with a mild strain. Other signs of a pulled calf muscle include mild swelling, sharp pain, bruising, redness behind the knee and lower leg, inability to stand or walk.


Treatment includes immediate first aid principles, which is to take active rest. It is important to allow the muscle to heal. Initially, it should be treated with RICE treatment. In the early acute stage, a knee compression bandage can help protect the muscle. Heat pads can help reduce swelling behind the leg. Additionally, stretching and strengthening programs can help calf strain heal faster. Typical recovery from gastrocnemius strain is six weeks. Before returning to sports activities and starting any exercise you must be able to walk pain-free.
