Achilles tendinopathy – Is it OK to train with pain?

Updated: Jun 12, 2019

The answer to this question lies somewhere between yes and no. In this article I’ll explain how I get my patients who have Achilles tendinopathy/tendonitis to distinguish between what level of pain is OK and when pain means that they should stop and rest.

Achilles tendinopathy or tendonitis – Is it OK to train with pain?

In this article:

  • What does the pain in your tendon mean?

  • The 24 hour response is important

  • Some pain/discomfort is absolutely fine

Do you prefer to watch rather than read? Here's a video I did about this:

What does the pain in your tendon mean?

When you injure any body part, you usually develop pain or discomfort. The pain acts as a warning that your brain would like you to please pay a bit more attention to that area and allow it to heal.

The problem is that our brains can sometimes amplify pain and make it feel more severe than what it should be. This often happens when we’re very worried about the implications of that injury – for example if that injury has the potential to affect your income or ruin an important race that you’ve been training for.

That’s why it’s important not to obsess about every twinge you feel in your Achilles tendon. Feeling pain/discomfort does not have to mean that you’re making your injury worse.

On the flipside I also find that some athletes, runners especially, are at risk of ignoring the pain in their Achilles tendons when they should in fact be listening to it. Things often niggle and hurt when you run. That’s normal and the harder you train the more discomfort you have to learn to deal with. I find that endurance athletes often aggravate their Achilles tendons through training because they genuinely don’t notice the pain until it’s too late.

This is why it’s extremely useful to work with a physio who can help you analyse your training programme, link that up with your symptoms and work out a recipe that you can use to guide your training – to decide how much pain is OK or not. I have to be honest, most athletes prefer to be in charge of their own training so my aim is always to help you identify your warning signs (they're different for different people) yourself and how you can tell if you’re training at the right level. If you get it right, you’ll be able to train and allow your Achilles to recover at the same time.

We offer an expert online physio service for treating ongoing Achilles tendon pain due to Achilles tendonitis or Achilles tendinopathy. Follow this link to learn more.

The 24 hour response is important

The interesting thing about injured tendons is that whilst you may feel some pain at the beginning of a training session, the pain often goes away while you’re training. It’s often only hours later or the next morning when you wake up that you realise that you may have overdone it and aggravated your injury.

This means that monitoring the pain that you feel at this moment in time is not the best way to tell if an activity will make your Achilles tendon pain worse. You have to really look at your symptoms over the next 24 hours. If there is no lasting increase in stiffness or pain, then it may mean that that training session/activity was OK to do.

Some signs that the training session was too much for your tendon include things like if you find you have to hobble more than the previous day or your Achilles takes longer to loosen off or it aches more.

Some pain/discomfort is absolutely fine

The research has consistently shown that it’s OK to get some pain in your Achilles while doing your strengthening exercises. In all the research studies that I’ve read about strength training and exercise for Achilles tendinopathy, the researchers have always allowed the participants to experience pain up to a level of 3/10 (where 0 is no pain and 10 is excruciating pain).

In practice I find that people struggle with “knowing” what 3/10 pain is for them. I find it works well if I tell them that it’s OK to have “some discomfort” while doing their exercises or running, but not what they class as pain. And as long as the discomfort stops within a few minutes of doing their exercises AND there is no increase in their symptoms during the next 24 hours (especially the next morning) it means that that level of pain or discomfort that they felt during training was absolutely fine. They can then use that as a gauge to guide their future training sessions.
