Haglund’s Deformity, a bony enlargement on the back of the heel that can lead to painful bursitis, is something that I have been dealing with for a very long time. It’s somewhat common amongst runners and is frequently misdiagnosed as achilles tendonitis. Believe me, it can be painful, as the soft tissue near the Achilles tendon becomes irritated when the bony enlargement rubs against the back of one’s shoes.
According to Wikipedia, the causes are due to some extent, to heredity. “People can inherit a type of foot structure that makes them prone to developing this condition.
“For example, high arches can contribute to Haglund’s deformity. The Achilles tendon attaches to the back of the heel bone, and in a person with high arches, the heel bone is tilted backward into the Achilles tendon. This causes the uppermost portion of the back of the heel bone to rub against the tendon. Eventually, due to this constant irritation, a bony protrusion develops and the bursa becomes inflamed. It is the inflamed bursa that produces the redness and swelling associated with Haglund’s deformity.
A tight Achilles tendon can also play a role in Haglund’s deformity, causing pain by compressing the tender and inflamed bursa. In contrast, a tendon that is more flexible results in less pressure against the painful bursa.
Another possible contributor to Haglund’s deformity is a tendency to walk on the outside of the heel. This tendency, which produces wear on the outer edge of the sole of the shoe, causes the heel to rotate inward, resulting in a grinding of the heel bone against the tendon. The tendon protects itself by forming a bursa, which eventually becomes inflamed and tender.”
Pain prevention can include stretching; a way to keep the Achilles tendon limber. Avoiding hills while running is another preventive cure; although it is not easy to do with the amounts of hills are on the island where I live, so I stretch and stretch. Taking pain relievers can be beneficial.
