Different types of tendonitis affect different parts of the body.
The Achilles tendon is between the heel and the calf muscle. Achilles tendinitis is a common sports injury. It may also be caused by shoes that fit badly or do not properly support the foot. It is more likely among patients with rheumatoid arthritis.
With supraspinatus tendinitis, the tendon around the top of the shoulder joint becomes inflamed, causing pain when the arm is moved, especially upwards.
Some patients may find it painful to lie on the affected shoulder at night. If other tendons in the same area are also affected, the patient may have rotator cuff syndrome.
Tennis or golfer’s elbow
A common symptom of lateral epicondylitis, commonly known as tennis elbow, is pain on the outer side of the elbow. It may radiate down towards the wrist.
Medial epidondylitis or golfer’s elbow is pain on the inner side of the elbow, and it is more common among golfers. Pain is more acute when trying to lift against a force. The pain sometimes radiates down to the wrist.
De Quervain’s stenosing tenosynovitis
The sheath that surrounds the thumb tendons, between the thumb and wrist, becomes inflamed. With the thickened sheath and swelling in the area, it becomes painful to move the thumb.
Trigger finger or thumb
The finger or thumb clicks when straightened out. It becomes fixed in a bent position because the tendon sheath in the palm of the hand is thickened and inflamed and does not allow the tendon to move smoothly. Sometimes a nodule forms along the tendon.
Tendonitis of the wrist
This can affect badminton players and production line workers, who repeatedly use the same motion with their wrist. Tendinopathy is another type of injury that affects the wrist tendons. This is a degenerative condition rather than an inflammation.
The symptoms of tendinitis include:
- Pain at the site of the tendon and surrounding area. Pain may gradually build up or be sudden and severe, especially if calcium deposits are present.
- Loss of motion in the shoulder, called “adhesive capsulitis” or frozen shoulder.
Symptoms occur where the tendon attaches to a bone.
They usually include:
- pain which worsens on movement
- a feeling that the tendon is crackling or grating as it moves
- swelling, heat, and redness
- a lump may develop along the tendon
If there is a rupture, a gap may be felt in the line of the tendon, and movement will be difficult.
Symptoms may last from a few days to several weeks or months.
