The Peroneal Muscles and Peroneal Tendonitis

The Peroneal Muscles and Peroneal Tendonitis: What You Need to Know

Let’s talk about the peroneal muscles—those important but often overlooked muscles running along the outer part of your lower leg. They’re essential for keeping your ankle stable and foot balanced, especially when walking, running, or standing on uneven surfaces. But what happens when they start acting up? That’s when you could be dealing with peroneal tendonitis, a condition that can cause pain and disrupt your daily activities. We’re going to explore what these muscles do, why tendonitis happens, and how therapies like massage cupping can help you get back on your feet.

What Are the Peroneal Muscles, Anyway?

The peroneal muscles, also known as the fibularis muscles, include three main muscles: the peroneus longus, peroneus brevis, and sometimes the peroneus tertius. The first two are the stars of the show when it comes to ankle and foot movement.

The peroneus longus starts at the upper part of the fibula (the smaller bone in the lower leg) and runs behind that bony bump on the outside of your ankle, called the lateral malleolus. From there, it goes underneath your foot to attach to the first metatarsal (near your big toe). It helps evert the foot (turn it outward) and assists in plantarflexion (pointing the toes downward).

The peroneus brevis, meanwhile, starts lower down on the fibula, also runs behind the lateral malleolus, and attaches to the base of the fifth metatarsal (the bone on the outer edge of your foot). It works similarly to the peroneus longus but has a slightly different line of pull.

The peroneus tertius, which not everyone has, helps with dorsiflexion (lifting the foot upward). If you’ve ever wondered why some people are more prone to ankle sprains, the stability these muscles provide is part of the answer.

What Is Peroneal Tendonitis, and Why Does It Happen?

Peroneal tendonitis is essentially an irritation or inflammation of the tendons connecting these muscles to the bones of the foot. It usually occurs when the tendons are overused or placed under stress, leading to tiny tears that cause pain. This condition is common among runners, hikers, and athletes who do a lot of side-to-side movements, like soccer players and basketball players.

Overuse is one of the main causes. If you suddenly increase your running mileage, start doing more high-impact activities, or spend a lot of time on uneven terrain, those tendons can get irritated pretty quickly. Improper footwear is another culprit. Shoes that don’t offer enough support can force the tendons to work harder than they should.

Other contributing factors include ankle instability (often from repeated sprains), biomechanical issues (like high arches or flat feet), and even tight calf muscles, which can place extra strain on the tendons. If you’re dealing with any of these, you might feel pain on the outside of your ankle, especially during activity, and it may worsen with time if left untreated.

What Does It Feel Like?

If you have peroneal tendonitis, you’ll likely notice pain and tenderness along the outer side of your ankle and foot, particularly behind that bony bump. Swelling is common, and the area might feel stiff, especially in the morning or after you’ve been sitting for a while. The pain usually flares up when you’re active and feels better with rest, but over time it may get worse, potentially leading to chronic discomfort or even tendon tears.

How to Treat Peroneal Tendonitis

So, what can you do if you’re dealing with this issue? The basics involve rest, icing the area, and avoiding activities that aggravate the condition. But for more targeted relief, there are therapies like massage cupping, manual therapy, and trigger point therapy that can help.

How Massage Cupping Can Help

Massage cupping is a technique where suction cups are placed on the skin to create negative pressure. This pulls blood to the surface, increasing circulation and bringing oxygen and nutrients to the tissues while helping remove waste products. It can be especially helpful for peroneal tendonitis because the suction helps release muscle tension and reduce inflammation along the outer calf and ankle.

There are two main methods for using massage cupping for tendonitis: static cupping, where the cups stay in one place, and gliding cupping, where the cups are moved along the muscle path. Both can help relax the peroneal muscles and improve flexibility, making it easier to manage the symptoms. For many people, incorporating cupping as part of their treatment routine provides significant relief and speeds up recovery.

What Else Can You Do?

Massage cupping isn’t the only tool you have at your disposal. Manual therapy techniques, like soft tissue mobilization, can help increase ankle range of motion and decrease muscle tightness around the peroneal tendons. Trigger point therapy can also be beneficial; it involves applying pressure to specific points in the muscle to release knots and tension.

Adding stretching and strengthening exercises into your routine can make a big difference, too. Focusing on the calf muscles and peroneal tendons will help improve flexibility and strengthen the support for your ankle. If you have biomechanical issues like high arches, you might want to look into custom orthotics to reduce the stress on your tendons.

Keeping the Peroneal Muscles Happy

It’s clear that the peroneal muscles play a crucial role in keeping your feet and ankles functioning well. If you’re dealing with peroneal tendonitis, don’t ignore it—it can worsen over time and become a bigger problem. Whether you try massage cupping, manual therapy, or other techniques, addressing the symptoms early on is the best way to prevent long-term issues.
