Achilles tendon injury
The Achilles tendon is the largest tendon in the human body. It connects the calf muscle to the heel bone. However, this tendon is also the most common site of rupture or tendonitis, an inflammation of the tendon due to overuse.
Achilles tendonitis is caused by overuse of the tendon and calf muscles. Symptoms may include mild pain after exercise that worsens gradually, stiffness that disappears after the tendon warms up, and swelling.
Plantar fasciitis
Plantar fasciitis is characterized by severe pain in the heel of the foot, especially when standing up after resting. The condition is due to an overuse injury of the sole surface (plantar) of the foot and results in inflammation of the fascia, a tough, fibrous band of tissue that connects the heel bone to the base of the toes. Plantar fasciitis is more common in women, people who are overweight, people with occupations that require a lot of walking or standing on hard surfaces, people with flat feet, and people with high arches. Walking or running, especially with tight calf muscles, may also cause the condition.
Ankle sprains
Ankle sprain is an injury to the foot’s ligaments in the ankle. Ligaments are tough bands of elastic tissue that connect bones to each other. Ankle sprains may occur if the ankle rolls, turns, or twists beyond its normal range of motion. Ankle sprains may be caused by awkward foot placement, irregular surfaces, weak muscles, loose ligaments, or wearing shoes with spiked heels. The symptoms of a sprain will depend on how severely the ligaments are stretched or torn, but usually include swelling, pain, or bruising.
Morton neuroma
Morton neuroma is a buildup of benign (noncancerous) tissue in the nerves running between the long bones of the foot. Morton neuroma occurs when two bones rub together and squeeze the nerve between them. Most often, neuromas develop between the bones leading to the third and fourth toes. Morton neuroma often causes swelling, tenderness, and pain. If the pain becomes severe, it may cause tingling, numbness, and burning in the toes. It usually occurs after standing or walking for a long period of time.
