Repetitive strain injury (RSI) is a general term used to describe the pain felt in muscles, nerves and tendons caused by repetitive movement and overuse.
The symptoms of RSI can range from mild to severe and usually develop gradually.
They often include:
• Pain, aching or tenderness
• Tingling or numbness
At first, you might only notice symptoms when you’re carrying out a particular repetitive task.
Without treatment, the symptoms of RSI may eventually become constant and cause longer periods of pain. You may also get swelling in the affected area, which can last for several months.
