Where does peritendinitis most often occur?

Peritendinitis most often develops in areas where tendons are put under a lot of strain. Common examples include the wrist, forearm, ankle, and the area around the Achilles tendon. Repeated, one-sided movements, such as those in sport, manual work, or computer use, can inflame the surrounding tissue. In some cases, even an unusual amount of activity is enough to trigger symptoms.

Causes and risk factors

Peritendinitis is usually caused by overuse or prolonged, repetitive movements. People who type a lot, lift heavy objects, or regularly take part in sports with quick changes of direction risk irritating the sensitive tendon tissue. Minor injuries, poorly fitting shoes, or incorrect training technique can also encourage inflammation. Less commonly, rheumatic conditions or certain infections are behind peritendinitis. In very rare cases, the problem can occur without any clear cause.

Symptoms and complaints

Typical signs of peritendinitis are a pulling or sharp pain along the affected tendon that gets worse with movement. The area is often swollen, red, or feels warmer than the surrounding tissue. Movement may be limited, and sometimes a rubbing or creaking sensation can be felt beneath the skin. In daily life, gripping, rolling the foot, or turning the wrist can be particularly difficult. If the inflammation is left untreated, symptoms can persist for weeks or even months.

Is peritendinitis dangerous?

A diagnosis of peritendinitis can sound worrying at first, but in most cases the inflammation is harmless and responds well to treatment. However, symptoms can significantly affect daily life, especially when the affected area is used frequently. Without adequate rest and treatment, there is a risk that the inflammation becomes chronic or spreads to nearby structures. Very rarely, complications can occur, such as lasting restricted movement or a weakening of the tendon.

What helps with peritendinitis?

The most important step is to rest the affected area and move it as little as possible. In the first few days, cooling the area can help reduce swelling and ease pain. Sometimes a bandage or splint is recommended to keep the tendon still. Anti-inflammatory medicines such as ibuprofen or diclofenac are often used to relieve symptoms. In some cases, a doctor may also prescribe special gels or creams.

Once the acute inflammation has settled, targeted physiotherapy can be helpful. This involves learning exercises that improve mobility and strengthen the muscles without irritating the tendon again. For persistent or particularly severe symptoms, further measures such as injections or, very rarely, surgery may be considered. In the vast majority of cases, however, peritendinitis heals completely within a few weeks.

What can you do yourself?

To support recovery, it helps to avoid strenuous movements for a period of time. Even small changes in daily routine, such as adjusting how you work, taking breaks during repetitive tasks, or using ergonomic aids, can make a big difference. For those who play sport, it is worth reviewing technique and correcting it where needed. Wearing suitable footwear can also help prevent problems, particularly around the ankle or Achilles tendon.

If symptoms persist for more than a few days despite rest and self-care, get worse, or are accompanied by noticeable swelling and redness, it is advisable to see a doctor. This helps to rule out other causes and ensures the right treatment is started.
