Plantar fasciitis is an inflammatory condition affecting the plantar fascia. The plantar fascia is a very inelastic fibrous band that covers the muscles in the foot. It inserts at the heel and extends to the toes, constituting an important support structure for the foot.
A muscle imbalance in the foot can cause stress on the plantar fascia. This can start an inflammatory process that leads to the development of localized heel pain and sometimes in the arch.
Your podiatrist will analyze your biomechanics to check if plantar fasciitis is caused by a misalignment. X-rays of the foot may also be necessary in order to analyze the bony structures.
Reviewing X-rays reveals sometimes the presence of a heel spur. This bone growth is the result of imbalance in the intrinsic muscles of the foot attaching at the heel. See your podiatrist to discuss treatment options.
