Achilles tendon pain and tendinopathy
The Achilles tendon is the strong band of tissue connecting your calf muscles to your heel. It helps you point your foot downwards, rise onto your toes and push off when walking or running. Over time, the tendon fibres can become weaker and less flexible. Small areas of damage can then develop, causing pain, stiffness and swelling. Achilles tendon pain is sometimes called tendinitis. However, it is more commonly linked to changes within the tendon rather than inflammation, so Achilles tendinopathy is usually the more accurate term.
What is Achilles tendinopathy?
The Achilles tendon is the strong band of tissue connecting your calf muscles to your heel. It helps you point your foot downwards, rise onto your toes and push off when walking or running. Over time, the tendon fibres can become weaker and less flexible. Small areas of damage can then develop, causing pain, stiffness and swelling. Achilles tendon pain is sometimes called tendinitis. However, it is more commonly linked to changes within the tendon rather than inflammation, so Achilles tendinopathy is usually the more accurate term.
What causes it?
There may be more than one reason why this develops. Possible causes or contributing factors include:
- A sudden increase or change in training
- Repeated strain from running or jumping
- Changes within the tendon over time
- Arthritis or another inflammatory condition
- In some cases, there is no obvious trigger
What are the symptoms?
Everyone experiences symptoms differently, but you may notice:
- Pain or stiffness along the tendon, particularly in the morning
- Pain at the back of the heel that becomes worse with activity
- Swelling that may increase throughout the day
- More severe pain the day after exercise
- Thickening of the tendon
How is it diagnosed?
Your consultant will examine your foot and ankle and ask when the pain began, how it has changed and which activities make it worse. An X-ray may show swelling or a bony lump. An MRI scan can provide more detail about the condition of the tendon.
We’ll explain any tests clearly and talk you through the results, so you understand what they mean for you.

Treatment routes
Most people improve without surgery. Treatment focuses on reducing pain, gradually rebuilding the tendon’s strength and helping you return safely to activity. Together, we’ll build a plan around your needs, your recovery and the activities that matter most to you.
- Temporarily reducing or changing painful activities
- A personalised physiotherapy programme
- Pain relief or anti-inflammatory medicine, if advised
- A small heel insert to reduce strain on the tendon
- Shockwave therapy in selected cases
Your consultant will help you understand which options may be right for you and when your progress should be reviewed.

How to pay
We offer flexible options depending on how you choose to access care at Fortius. Whichever option you choose, we’ll help make the process clear and straightforward from the start.

Private medical insurance
If your care is covered by private medical insurance, we’ll usually invoice your insurer directly. Please check your policy in advance and request an authorisation code if your insurer requires one. You’ll be responsible for paying any policy excess or costs that aren’t covered by your insurance.

Paying for yourself
You don’t need private medical insurance to access care at Fortius. If you’re paying for your own treatment, our team will explain the costs clearly and provide a personalised quote before you decide whether to go ahead.
