Just like joints, tendons are also subject to wear and tear, or “degeneration”. When it occurs in the Achilles tendon, it can result in pain and swelling or sometimes rupture of the tendon.
Typically there is increased pain during or after running or walking. Some people suffer painful flare-ups lasting for days/weeks, with the symptoms subsiding in between these flare-ups.
The exact cause of the condition is not known, and it can be difficult to treat. When you hear of a professional athlete having a “niggling Achilles injury”, this is usually Achilles tendinosis.
HOW CAN IT BE TREATED?
Treatment of a flare-up is rest.
There are a number of ways of resting the tendon:
- Reduce running/walking
- Heel lift shoe inserts
- Immobilisation in a cast or “walker boot”
Additionally, your doctor may recommend anti-inflammatory painkillers during a flare-up, especially if there is redness and swelling.
The mainstay of treatment is prevention of flare-ups, however. A number of treatments have been tried, including laser, ultrasound, electrical stimulation and shock-wave therapy. The most effective treatment is thought to be a particular regime of stretching exercises, called Eccentric Strengthening1. This strict regime can be up to 95% effective in 3 months.
