What are the symptoms of repetitive strain injury?
Repetitive strain injury (RSI) symptoms in the affected area can include:
- Dull ache
The symptoms tend to develop gradually. At first the symptoms may only occur whilst you do the repetitive task and ease off when you rest. In time the symptoms can be present all the time but tend to be made worse by doing the repetitive task. Symptoms can range from mild to severe.
Some people divide RSI into two main categories: Type 1 RSI and Type 2 RSI.
Type 1 RSI
This includes well-defined syndromes such as:
- Carpal tunnel syndrome: pain and squashing (compression) of a nerve in the wrist.
- Tendinopathy: inflammation of a tendon.
- Tenosynovitis: inflammation of a tendon sheath.
See separate leaflets called Carpal Tunnel Syndrome and Tendinopathy and Tenosynovitis for more details. These conditions may be due to, or be made worse by, repetitive tasks. However, these syndromes are also common in people who have not done repetitive tasks. These syndromes may have other symptoms such as swelling, inflammation, nerve compression problems, etc.
Type 2 RSI
This is where symptoms do not fit into a well-defined syndrome. Also, there are no objective or measurable signs such as inflammation, swelling or problems with nerve function. It is sometimes called diffuse RSI or nonspecific pain syndrome.
