Achilles Tendinopathy

Explanation of Diagnosis

Achilles tendinopathy is an overuse problem affecting the Achilles tendon, the strong cord at the back of your ankle that helps you push off when walking, running, or climbing stairs. It often develops when the tendon is repeatedly loaded faster or more than it can recover, leading to irritation, thickening, and pain with activity. Symptoms commonly include pain along the tendon (often a few centimeters above the heel), morning stiffness, and discomfort during walking, hills, stairs, or exercise. Some people also notice a tender “spot,” swelling, or reduced strength compared with the other side.

Specific Work Modifications

• Limit long bouts of walking or standing when symptoms flare, and add short sit breaks as needed
• If you work on your feet, use supportive shoes and consider an insert designed to reduce strain at the Achilles
• Avoid steep hills, repeated stair climbing, or walking with a heavy load during higher-pain days
• Choose tasks with flatter surfaces when possible, and temporarily rotate duties to reduce repeated push-off
• Use a chair or footrest to keep your ankle from staying strongly pointed for long periods (like on some low desks)
• If lifting or carrying is required, keep loads close to your body and avoid fast changes in pace that trigger sharp tendon pain

Specific Activity Modifications

• Temporarily reduce or pause running, jumping, and hill workouts while pain is actively flaring
• Choose flatter routes for walking, and shorten step length if that helps reduce tendon pain
• Avoid deep calf stretching if it sharply increases symptoms, and reduce intensity before adding volume back
• Prefer cycling or swimming over impact activities if they can be done with minimal tendon pain during and after
• Gradually return to sports by increasing time or load slowly, rather than adding both at once
• If stairs or getting in/out of a car triggers symptoms, take them one at a time and slow down during the first week of flare control

Recommended Supplements

• Omega-3 fish oil (about 1,000 to 2,000 mg per day of combined EPA and DHA) may help support a more balanced inflammatory response during tendon recovery
• Collagen peptides (about 10 g per day) may support connective tissue health when combined with good tendon-loading rehab
• Turmeric/curcumin (about 500 to 1,000 mg per day) may help some people with pain modulation and recovery support, but stop if it upsets your stomach

Recommended Nutrition and Hydration

Diet Recommendations

• Aim for adequate protein (often roughly 20 to 35 g per meal, depending on your body size and appetite) to support tendon repair
• Choose a colorful mix of fruits and vegetables to provide micronutrients that support healing
• Include healthy fats such as olive oil, nuts, seeds, and fatty fish to support tissue recovery
• Limit alcohol and highly processed foods during active flares, since they can worsen overall recovery
• If you have diabetes, kidney disease, or a restricted diet, follow your clinician’s guidance on nutrition changes

Hydration Tips

• Drink enough fluids so your urine is typically light yellow, especially if exercise is reduced but you are still active
• Even mild dehydration can worsen muscle/tendon discomfort, so keep water available during daily activity
• If you sweat a lot, include electrolytes through food (and fluids) rather than relying on very salty snacks

Home Exercise Prescription

Perform these exercises about 4 to 5 days per week, with symptoms used as your guide.

1. Isometric calf squeeze: Stand facing a wall or hold a counter for balance, rise up slightly and press into the ground without moving your heel much; hold 30 to 45 seconds, repeat 4 to 5 times
2. Seated calf stretch (gentle): Sit with the sore leg forward, pull toes toward you until you feel a mild stretch in the calf (not sharp pain); hold 30 seconds, repeat 3 to 5 times
3. Standing calf raises (double-leg, pain-guided): Rise up slowly, pause briefly at the top, then lower slowly; do 2 to 3 sets of 8 to 12 reps within a tolerable pain range
4. Towel-assisted range of motion: Sit and gently pull the foot through comfortable ankle motion, from neutral to mild stretch only; do 1 to 2 sets of 10 to 15 slow moves
5. Tendon-friendly walking progression: Short, flat walks with supportive shoes, increasing time by only a small amount if symptoms settle within 24 hours; start with 5 to 10 minutes and build as tolerated

Stop and reassess if you get sharp, worsening pain, a sudden increase in swelling, or pain that spikes and does not settle within the next day.
