That sharp or nagging pain at the back of your heel when you climb stairs, push off while walking, or finish your morning walk is often the Achilles tendon complaining. The Achilles tendon, sometimes called the heel cord, is the strongest tendon in your body. It connects your calf muscles to your heel bone and lets you rise on your toes, run, and jump. When it gets irritated and inflamed, the condition is called Achilles tendinitis. The good news is that most cases respond very well to physiotherapy without injections or surgery.
Achilles tendinitis is an overuse injury of the heel cord. Repeated stress causes tiny tears in the tendon faster than the body can repair them, leading to pain, stiffness, and swelling. It usually develops gradually over weeks rather than appearing suddenly.
There are two main types:
- Insertional Achilles tendinitis: Pain where the tendon attaches to the heel bone, often with a tender bony bump.
- Mid-portion (non-insertional) Achilles tendinitis: Pain in the middle of the tendon, about two to six centimetres above the heel. This is the more common type in active adults.
In our clinic in JP Nagar, Bangalore, we see Achilles tendinitis across all ages. These are the usual culprits:
- Sudden increase in activity: Starting a walking or jogging routine after years of sitting, especially common among IT professionals who go from desk-bound weekdays to ambitious weekend workouts.
- Flat footwear: Everyday flat chappals and sandals offer no heel cushioning or arch support, increasing strain on the tendon during long hours of standing or walking.
- Tight calf muscles: Long sitting hours shorten the calves, reducing ankle flexibility and loading the tendon more with each step.
- Hard surfaces: Running or brisk walking on concrete roads and tiled floors adds impact the tendon must absorb.
- Weekend sports: Badminton, cricket, and football bursts involve sprinting and jumping that overload an unprepared tendon.
- Age and weight: The tendon weakens with age, and excess body weight multiplies the load with every step. Both are increasingly common in urban India.
- Medical factors: Diabetes, high cholesterol, psoriasis, and certain antibiotics (fluoroquinolones) can weaken the tendon.
Typical signs of Achilles tendinitis include:
- Pain and stiffness at the back of the heel, worst in the first steps after waking up or after long sitting.
- Tenderness when you pinch the tendon between thumb and fingers.
- Pain that warms up with activity but returns worse afterwards.
- Mild swelling or a thickened, cord-like feeling in the tendon.
- Weakness or discomfort when rising onto your toes.
Seek medical attention urgently if you hear or feel a sudden pop in the back of your heel, cannot push off or stand on tiptoe, or have severe sudden pain with bruising. These suggest an Achilles rupture, which needs prompt specialist care. Also see a professional promptly if pain persists beyond two weeks despite rest.
The evidence is clear: structured physiotherapy is the first-line treatment for Achilles tendinitis, not rest alone and not painkillers long term. A typical recovery plan includes:
- Relative rest and load management: Reduce aggravating activities but keep moving. Complete rest weakens the tendon further.
- Ice and comfort measures: Ice for 10 to 15 minutes after activity eases pain. A small heel lift in both shoes can temporarily reduce tendon strain.
- Manual therapy: Soft tissue work for the calves and joint mobilisation of the ankle restore movement and reduce load on the tendon.
- Calf flexibility: Gentle stretching once acute pain settles.
- Progressive strengthening: The heart of treatment, explained below.
- Gait and footwear advice: Correcting running form, replacing worn-out shoes, and moving away from flat chappals for long days.
These exercises form a progressive plan. Start at Phase 1 and move to the next phase only when the current one is comfortable. Expect the full programme to take eight to twelve weeks; tendons heal slowly because they have poor blood supply.
- Isometric calf holds: Stand facing a wall, rise onto both toes to a pain-free height and hold for 30 seconds. Rest 30 seconds. Repeat 5 times, twice daily. Isometrics reduce tendon pain and maintain strength.
- Ankle pumps and alphabet: Gently move the foot up and down and trace letters in the air to keep the joint mobile.
Eccentric training is the gold standard for mid-portion Achilles tendinitis.
- Stand on a step with the balls of your feet on the edge, heels hanging off. Hold a railing for balance.
- Rise onto your toes using both legs.
- Shift weight to the affected leg and slowly lower the heel over four to five seconds below the step level.
- Use the good leg to rise again. Do 15 repetitions, 3 sets, twice daily.
For insertional tendinitis, start with heel drops on flat ground and avoid dropping below the step level early on, since deep dorsiflexion can irritate the heel bone insertion. Mild discomfort during exercise is acceptable; sharp next-day worsening means reduce the dose.
- Single-leg heel raises: Rise onto one toe, taking three seconds up and three seconds down. 3 sets of 12 to 15 reps, progressing to 20.
- Seated calf raises: Targets the soleus muscle with a weight or resistance band over the knees. 3 sets of 15.
- Step-ups and mini squats: Build overall leg strength and control.
- Reintroduce brisk walking, then gentle jogging intervals (one minute jog, two minutes walk).
- Add skipping rope or light hopping drills to retrain spring-like tendon function.
- Return to sport only when single-leg heel raise volume equals the other side and daily activities are pain free.
- Gastrocnemius stretch: Hands on wall, back leg straight, back heel down, lean forward 30 seconds each side.
- Soleus stretch: Same position but bend the back knee, keeping the heel down. Hold 30 seconds.
- Plantar fascia roll: Roll the foot over a chilled bottle for two minutes to ease morning stiffness.
Do these twice a day, especially before bed if mornings are stiff.
- Switch to supportive, slightly heeled footwear for work instead of flat chappals.
- If you sit for eight or more hours, stand and do ten gentle calf raises every couple of hours.
- Manage blood sugar and cholesterol, both of which affect tendon healing.
- Maintain a healthy weight; every extra kilo adds roughly three kilos of force through the tendon while running.
- Warm up for five minutes before sport, and increase weekly training distance by no more than ten percent.
Give home exercises two weeks if symptoms are mild. See a physiotherapist sooner, or immediately, if pain affects your walking, keeps recurring every time you restart exercise, or if you notice a growing bump at the heel. A proper assessment identifies whether it is insertional or mid-portion tendinitis, rules out partial tears, and tailors the strengthening plan to your stage. Chronic untreated tendinitis can progress to tendinosis (degeneration) or even rupture, so early treatment pays off.
At PhysioFix in JP Nagar, Bangalore, Dr.Nishmitha.R assesses heel cord pain with a detailed movement and strength examination, then builds a personalised eccentric-loading and return-to-activity programme, with hands-on therapy where needed.
With consistent physiotherapy, most people improve significantly in six to twelve weeks. Long-standing cases can take three to six months because tendon remodelling is slow.
No. Total rest slows tendon recovery. Keep pain below three out of ten during activity and adjust your walking distance accordingly.
Yes, but modified. Start on flat ground without dropping the heel below the level, and progress depth gradually under supervision.
Usually not. Diagnosis is clinical. Imaging is reserved for suspected rupture or cases not responding to three months of proper rehabilitation.
Heel cord pain rarely fixes itself by waiting. With the right loading plan, your Achilles can become stronger than before. If heel pain is limiting your day, book an assessment and get started on a plan built for your feet, not a generic handout.
