Tendonitis is when a tendon swells up and becomes painful after a tendon injury. You can treat mild tendon injuries yourself and should feel better within 2 to 3 weeks.
How to treat tendonitis yourself
Follow the 4 steps known as RICE therapy for 2 to 3 days to help bring down swelling and support the injury:
- Rest - stop the exercise or activities that caused the injury until you feel better
- Ice - put an ice pack (you could use a bag of frozen peas wrapped in a teatowel) on the injury for up to 20 minutes every 2 to 3 hours
- Compress - wrap a bandage around the injury to support it
- Elevate - if possible, keep the injured area raised on a pillow when sitting or lying down
To help prevent swelling during the first 2 to 3 days, try to avoid:
- heat, such as hot baths and heat packs
When you can move the injured area without pain stopping you, try to keep moving it so the tendon doesn’t become stiff.
Your pharmacist can help with tendonitis
Your pharmacist can recommend the best painkiller. This might be tablets or a cream or gel you rub on the skin.
Paracetamol and ibuprofen can help to ease mild pain. Wait for 48 hours after your injury before taking ibuprofen, because it can slow down healing.
Check if it is tendonitis
There are tendons all over your body. They connect your muscles to bones, for example in your knees, elbows and shoulders.
The main symptoms of tendonitis are:
- pain in a tendon (for example, in your knee, elbow or shoulder) which gets worse when you move
- difficulty moving the tendon
- feeling a grating or crackling sensation when you move the tendon
- swelling, sometimes with heat or redness
- a lump along the tendon
There are many different types of tendonitis, depending on which area of the body is affected.
Types of tendonitis
|Affected area||Possible types of tendonitis|
|Knees||patellar tendonitis (jumper’s knee)|
|Elbows||tennis elbow or golfer’s elbow|
|Shoulders||calcific tendonitis or supraspinatus tendonitis|
|Wrists and thumbs||de Quervain’s disease|
|Upper arm||biceps tendonitis|
Go to a minor injuries unit or your GP if:
- your symptoms don’t improve within a few weeks
- you’re in a lot of pain
- you think you’ve ruptured (torn) a tendon
A ruptured tendon usually causes sudden and severe pain. You might hear a popping or snapping sound during the injury.
Treatment from your GP
Your doctor may prescribe a stronger painkiller or cream or gel to bring down the swelling.
If your injury is severe or lasts a long time, you may be offered physiotherapy. You can also choose to book appointments privately.
You may be referred to hospital for a scan if your doctor thinks you could have another injury, such as a broken bone.
Some people with long-term or severe tendonitis may be offered:
- steroid injections to reduce pain and swelling
- shock wave therapy to help speed up healing
- surgery to remove damaged tissue or repair a ruptured tendon
You can’t always prevent tendonitis
Tendonitis is most often caused by sudden, sharp movements or repetitive exercise, such as running, jumping or throwing.
To help reduce your risk of tendon injuries:
- warm up before exercising and stretch afterwards
- wear suitable shoes for exercise
- take regular breaks from repetitive exercises
- over-exercise tired muscles
- start a new sport without some training or practice
- stick to the same repetitive exercises
If you can’t speak to your GP or don’t know what to do next.
