Plantar Fasciitis is a condition that leads to pain in the bottom of the heel. Please note that the plantar fascia is a weblike, thick ligament that links the heel to the foot’s front. Besides, it also behaves as a shock absorber and provides support to the foot’s arch, which aids walking.
The plantar fascia in humans face lots of wear and tear when performing regular activities. High levels of pressure on the feet can cause a high level of damage or tear up the ligaments. The plantar fascia becomes swollen, causing a great deal of pain and stiffness in the heel.
In the meantime, the primary cause of plantar fasciitis hasn’t been discovered. According to a 2003 study, the condition may involve degeneration instead of the plantar fascia’s known inflammation. According to the National Institute for Health and Care Excellence, plantar fasciitis is responsible for around 80% of heel pain cases. 
Here are some eight of the major causes of plantar fasciitis:
Plantar fasciitis is a common condition among individuals between the age of 40 to 60 years. However, it may also occur in people of different ages. In one study of adults greater or equal to fifty years, it was discovered that the population prevalence of plantar heel was high among adults around the age of fifty years and above. 
Several medical conditions are associated with people of old ages. Some examples of medical conditions that may be linked to age include hearing loss, refractive errors, neck pain, back pain, diabetes, dementia, and more. Fortunately, older adults can make lifestyle changes to control plantar fasciitis.
