Achilles Tendon Pain: Causes and Treatment
If you've been favouring one heel lately, wincing on the first few steps out of bed, or noticing a dull ache creep in partway through a hike, there's a good chance your Achilles tendon is trying to tell you something. It's a common complaint we see at Kootenay Pedorthic Clinic, and it's also one of the most misunderstood — people tend to either ignore it until it's screaming, or assume rest alone will fix it.
The good news is that it responds well to the right approach. This post is for anyone who's been pushing through that nagging pull at the back of the heel and wondering what's actually going on.
What Is Achilles Tendon Pain?
The Achilles tendon connects your calf muscles to your heel bone, and it takes on an enormous amount of load with every step you take, often several times your body weight. When that tendon is repeatedly asked to handle more stress than it's currently conditioned for, it becomes irritated, and the fibres can start to break down faster than they repair. That's Achilles tendinopathy, and where it shows up matters: pain right at the heel is a different pattern than pain a few centimetres up the back of the leg, and it changes how we approach both assessment and treatment.
What Does It Actually Feel Like?
Most people describe a dull ache or stiffness at the back of the heel or lower calf, often worse first thing in the morning or after periods of rest. It tends to ease up once you're moving, which is exactly why it gets ignored early on. Over time, it can progress to sharper pain during activity, tenderness to the touch, or noticeable thickening of the tendon itself. If you're noticing that pattern building, it's worth paying attention to.
Why Does It Happen?
There's rarely one single cause. Achilles pain tends to develop when a combination of factors puts more load on the tendon than it can comfortably manage over time. Some of the things we look at during an assessment:
Foot mechanics - If your foot rolls in excessively (overpronation) or your arch collapses under load, the Achilles gets pulled at an angle it isn't built to handle repeatedly.
Calf and ankle tightness - A tight gastroc-soleus complex changes how much strain lands directly on the tendon with every step.
Footwear - A shoe with a worn-out midsole or an unsupportive heel counter can quietly increase Achilles loading for weeks before it catches up to you.
Activity changes - A sudden jump in training volume, whether that's hiking, running, or standing more at work, is a common way to trigger it.
How We Treat Achilles Tendon Pain
The first thing we do is figure out what's actually driving it for you specifically. Two people can come in with the same complaint and have completely different underlying causes, so the treatment plan needs to reflect that.
Here's what treatment typically looks like at Kootenay Pedorthic Clinic:
Custom orthotics - For many people, a well-designed custom orthotic is a key piece of managing Achilles load. The goal is to help control excess pronation and reduce the angle of pull on the tendon, giving it a better chance to settle. Because our orthotics are built from a physical cast of your foot around your specific biomechanics, they address the mechanical factors contributing to your particular case.
Footwear assessment - Part of what we do is look at what you're wearing day-to-day, including heel support and heel-to-toe drop. In some cases, a footwear change alone makes a noticeable difference before orthotics are even needed.
Load management guidance - Tendons respond to a gradual, progressive increase in load over time. We'll talk through how to keep moving without continuing to aggravate things, and roughly what a sensible progression looks like for your situation.
What Happens If You Ignore It?
Achilles pain doesn't tend to get better on its own when the underlying causes are still there. Left unaddressed, it tends to become more stubborn, take longer to settle, and in some cases increases the risk of a more serious tendon injury.
The earlier you address it, the easier it is to treat. Most people who come in when symptoms are relatively new respond well and fairly quickly. People who've been dealing with it for months often need more time and a more involved approach.
When to Come In
If you've had Achilles pain for more than a few weeks, or if it's changing how you walk or move through your day, it's worth coming in for an assessment. You don't need a referral to see us, and we're happy to answer questions before you book if you're not sure whether we're the right fit.
