Plantar fasciitis and Achilles tendonitis are two common conditions that affect the feet and ankles. Although they can have similar symptoms, they differ in terms of the location of the pain and the affected structures.
Plantar fasciitis is a condition that affects the plantar fascia, a thick band of tissue that runs from the heel bone to the toes. It is characterized by pain in the heel or arch of the foot, especially when taking the first steps in the morning or after prolonged periods of sitting or standing. The pain may also worsen with physical activity or when standing on hard surfaces. Plantar fasciitis is typically caused by repetitive strain on the plantar fascia, such as from running, jumping, or walking on hard surfaces.
Achilles tendonitis, on the other hand, is a condition that affects the Achilles tendon, which is the largest tendon in the body and connects the calf muscles to the heel bone. It is characterized by pain and stiffness in the back of the heel or calf, especially when walking, running, or jumping. The pain may also be accompanied by swelling and tenderness. Achilles tendonitis is typically caused by overuse or injury to the Achilles tendon, such as from sudden increases in activity, wearing improper footwear, or engaging in activities that require sudden stops or changes in direction.
In summary, plantar fasciitis affects the plantar fascia and causes pain in the heel or arch of the foot, while Achilles tendonitis affects the Achilles tendon and causes pain in the back of the heel or calf. The treatment for each condition may differ, so it is important to see a healthcare professional for an accurate diagnosis and appropriate management.
