Tenosynovitis: Inflammation in the Hands and Feet

· September 30, 2016
Tenosynovitis can become severely debilitating. As such, it's important that we know how to identify its symptoms as soon as possible. Doing so will ensure an early diagnosis and proper treatment.

The word tenosynovitis may sound a little strange. But in reality, it’s a problem that many of our readers will become familiar with at some point.

It’s the inflammation of the lining of the protective sheath that surrounds the tendon. It’s painful, debilitating and is centralized in the hands and feet.

It may occur as sudden swelling of the skin and redness of the skin may occur as well. Despite not having suffered any injury, the pain is intense and debilitating, even when at rest.

Experts tell us that getting an early diagnosis is vital. This will prevent the inflammation from further damaging tendons and their sheaths and causing even more problems.

If you are feeling discomfort, consult a specialist. Below, we’ll tell you everything you need to know about tenosynovitis.

Tenosynovitis: debilitating joint pain

In order to understand what tenosynovitis is, let’s take a look at a tendon. This perfect structure anchors the muscles in our hands to the bone.

The tendon is covered in a sheath, the synovial membrane, which protects and isolates the tendons. This is precisely where the inflammation and pain occur.

What’s notable right away about this condition is that it affects the flexor muscles. This means the first symptoms occur when moving your hands or walking.

It begins as a slight pain, but slowly it develops into inflammation, swelling, and even fever.

What causes it?

The main causes of inflammation of the synovial sheath are repetitive movements of the hands and feet. Poor posture also plays a contributing role.

Every one of these repetitive and constant movements causes excessive friction between the tendon and bone. Repetitive movement and small injuries to the sheath that surrounds the tendon can slowly lead to swelling. 

De Quervain syndrome

One of the most common injuries associated with tenosynovitis is De Quervain syndrome.

It’s a painful inflammation of the tendons in the thumbs.

  • Everyday tasks like picking up a small child, sewing, typing, or even playing the piano can cause it.
  • It can also be from physical injury to the thumb, such as a small, subtle tear in the tendon. It may be painful, but as time passes this tissue scars.
  • The scar tissue can prevent the tendon from functioning well. This is something to keep in mind that can also cause De Quervain syndrome.

Treatment for chronic tenosynovitis

The main treatment goal is to reduce inflammation. Your doctor will discuss the best course of treatment for you.

Combining drugs with physical rehabilitation is the most common treatment.

  • You must keep your hand or foot immobile for a few days with a splint or bandage.
  • Hot and cold therapy is also effective.
  • Soaking the affected area in warm rosemary water will relax your muscles and relieve inflammation.
  • Ginger tea is also highly recommended. It reduces pain and swelling.
  • Physical therapy is a huge help for treating tenosynovitis. You’ll also learn exercises that you can do at home to restore strength and mobility.

These basic treatments are to reduce stress and pressure on the tendons.
