Posterior Tibialis Tendonitis: Why Shockwave Therapy Gets You Back on Your Feet
If the inside of your ankle aches every time you walk, run or stand for long periods, and your arch seems to be flattening out, you may be dealing with
posterior tibialis tendonitis. It is one of the most commonly missed causes of inner ankle and arch pain, and when it is left alone it can progress into a flatfoot deformity that is much harder to fix.
The good news: posterior tibialis tendonitis responds very well to the right treatment. At Pursuit Physical Therapy in Orlando and Winter Garden, we combine
focused shockwave therapy with hands-on, one-on-one physical therapy to calm the pain, heal the tendon and get you back on your feet for good.
What Is Posterior Tibialis Tendonitis?
The posterior tibialis muscle runs down the back of your shin. Its tendon wraps behind the bony bump on the inside of your ankle (the medial malleolus) and attaches to the bottom of your foot. Its main job is to
hold up your arch and control how your foot rolls in every time you take a step.
When that tendon is overloaded faster than it can adapt, it becomes irritated, weakened and painful. Clinicians increasingly call this
posterior tibialis tendinopathy, because in most cases the problem is tendon breakdown, not just inflammation. It is also the most common cause of adult-acquired flatfoot.
Common symptoms
- Pain and tenderness along the inside of the ankle, just behind or below the ankle bone
- Swelling along the inner ankle
- Pain that worsens with walking, running, hiking, stairs or standing all day
- An arch that feels like it is collapsing, or a foot that rolls in more than it used to
- Difficulty or pain rising up onto the toes of the affected foot
- Fatigue or aching in the arch by the end of the day
Who gets it?
We see posterior tibialis tendonitis most often in runners and walkers who increase mileage too quickly, people who stand on hard floors at work, active adults over 40, and anyone with flat feet or a history of ankle sprains. Theme park employees, nurses, teachers, pickleball and tennis players are all regulars in our clinics with this problem.
Why It Lingers (and Why Rest Alone Doesn’t Fix It)
Most people try the usual playbook first: rest, ice, anti-inflammatories, maybe a brace or a new pair of shoes. Those can take the edge off, but they rarely solve the problem. Here is why:
- Tendons have a limited blood supply, so they heal slowly on their own.
- Rest unloads the tendon but doesn’t rebuild it. The pain fades, you go back to activity, and it flares up again.
- The root cause goes unaddressed. Weak hips and calves, poor foot mechanics and training errors keep overloading the same tendon.
- Cortisone injections near tendons carry risk. They can weaken tendon tissue, which is the last thing an already strained tendon needs.
That is why so many people come to us after months of “it’ll go away on its own.” A chronic tendon needs a stimulus to heal and a plan to get stronger. That is exactly where shockwave therapy and specialized physical therapy come in.
How Shockwave Therapy Helps You Get Pain-Free
Extracorporeal shockwave therapy (ESWT) uses high-energy acoustic waves delivered through the skin directly into the injured tendon. It is non-invasive, needs no needles, no medication and no downtime, and each session takes only about 10 to 15 minutes.
Shockwave works so well for stubborn tendon problems because it does more than mask pain. It helps restart the healing process:
- Increases blood flow. Shockwave stimulates the formation of new blood vessels in the tendon, bringing oxygen and nutrients to tissue that is normally slow to heal.
- Triggers tissue repair. The mechanical stimulus signals your body to produce new collagen and remodel the damaged tendon fibers.
- Calms pain signals. Shockwave reduces pain-signaling chemicals and desensitizes irritated nerve endings, so many patients feel relief within the first few sessions.
- Breaks the chronic cycle. By turning a stalled, chronic injury back into an active healing response, it gives the tendon a real chance to recover.
What to expect
A typical shockwave plan is 3 to 6 sessions spaced about a week apart. You will feel a strong tapping sensation over the tendon during treatment, and you can walk out and go about your day afterward. Most patients notice meaningful improvement over the course of treatment, with healing continuing in the weeks after the final session.
Shockwave is most effective when it’s paired with the right exercise program. That combination is what we specialize in.
Our Approach: Shockwave + Specialized Physical Therapy
At Pursuit, shockwave is one powerful piece of a complete plan built around you:
- A thorough evaluation. We assess your foot, ankle, calf, knee and hip mechanics, your activity and your footwear to find out why your tendon got overloaded.
- Focused shockwave therapy to jump-start healing in the tendon and bring down pain.
- Progressive tendon loading. Targeted strengthening for the posterior tibialis, calf and foot muscles that rebuilds tendon capacity, the single most important factor in long-term recovery.
- Hip and core strengthening to improve how your leg absorbs load with every step.
- Manual therapy and dry needling when appropriate to ease tight, painful tissue around the ankle and calf.
- Footwear, orthotic and activity guidance so you can keep running, training, working and living while you heal.
- A return-to-activity plan so the problem doesn’t come back.
Every visit is one-on-one with a Doctor of Physical Therapy for the full session. No aides, no bouncing between three patients at once.

Frequently Asked Questions
Does shockwave therapy hurt? You’ll feel a strong tapping sensation over the tendon. Most patients describe it as uncomfortable but very tolerable, and we adjust the intensity to your comfort level.
How many sessions will I need? Most patients need 3 to 6 shockwave sessions, about a week apart, alongside a targeted exercise program. Your therapist will lay out a plan at your first visit.
Can I keep running or working out during treatment? In most cases, yes, with modifications. We’ll guide you on what to keep doing and what to pause so you stay active while the tendon heals.
Do I need a referral or an MRI? No. You can book directly with us. We’ll perform a thorough evaluation and let you know if any imaging or a physician referral is needed.
What happens if I ignore it? Posterior tibialis tendonitis can progress to tendon dysfunction and a collapsing arch (adult-acquired flatfoot), which is much harder to reverse. Early treatment makes a big difference.
