Achilles Tendonitis is inflammation or irritation of the Achilles tendon, the thick, strong cord connecting your calf muscles to your heel bone. Frequently seen among runners, athletes, and active individuals, this condition causes persistent heel pain, stiffness, swelling, and tenderness, significantly restricting daily activities and athletic performance. Without proper care, Achilles tendonitis can become chronic, making everyday tasks uncomfortable and difficult. However, recognizing symptoms early and adopting appropriate treatments—such as targeted stretches, supportive footwear, bracing, and lifestyle modifications—can help alleviate discomfort, accelerate healing, and prevent future injury.
Heel pain can stem from several conditions. Use the comparison below to help determine what's causing your discomfort and how best to treat it.
Condition | Pain Location | When Pain Occurs | Symptoms | Common Causes |
---|---|---|---|---|
Achilles Tendonitis | Back of heel, above heel | After activity, prolonged standing or movement | Swelling, stiffness, tenderness in tendon | Running, jumping, sudden increase in activity, tight calves |
Plantar Fasciitis | Bottom of heel, near arch | First steps in the morning or after rest | Sharp, stabbing pain that eases after moving | Poor footwear, standing long periods, obesity, high-impact sports |
Heel Spurs | Bottom or back of heel | During or after prolonged standing/activity | Dull ache, feels like stepping on a stone | Chronic plantar fasciitis, repetitive foot strain |
Stress Fracture | General heel or foot pain | During weight-bearing activities, gradually worsens | Tenderness, swelling, persistent worsening pain | Running, repetitive impact sports, weakened bones |
Bursitis (Heel) | Back or underside of heel | With ankle movement or pressure | Swelling, tenderness, warmth in heel area | Tight footwear, repetitive ankle motion, direct heel trauma |
A healthcare professional typically conducts a physical exam, checking for tenderness, swelling, and limited range of motion. They may also perform imaging tests such as:

Achilles tendonitis pain typically appears at the back of the heel or lower calf, worsening with activities like running or climbing stairs. Plantar fasciitis usually produces sharp, first-step heel pain in the morning or after rest. A physical exam and checking tenderness points can help distinguish the two, but a healthcare professional’s evaluation is best for an accurate diagnosis.
Mild Achilles tendonitis typically improves in 4-6 weeks with rest and treatment. Moderate to severe cases can take 3-6 months or longer, especially if untreated or continually aggravated.
Rest, ice therapy, stretching exercises, and wearing supportive braces or night splints are highly effective. In particular, using a night splint like the Brace Direct 90 Degree Night Splint helps speed recovery by gently stretching the tendon overnight.

Gentle massage can help improve circulation and reduce stiffness, but avoid deep or aggressive massage, which could worsen inflammation or irritation.
Sudden increases in physical activity, high-impact sports, inadequate stretching, improper footwear, or repeatedly ignoring mild symptoms can significantly worsen Achilles tendonitis.
