What Exactly Causes Plantar Fasciitis

Standard

Overview

Plantar fasciitis is an inflammation of the structures (of the plantar fascia) on the sole of the foot. The inflammation is caused by excess pressure on the structures on the sole of the foot. The plantar fascia becomes inflamed and tiny rips can occur where it attaches into the inside of the heel bone. It tends to be most painful first thing in the morning, or when standing up after sitting for a while. The area becomes inflamed and swollen, and it is the increase in fluid to the area that accumulates when weight is taken off the area, that then causes the pain on standing. Plantar Fasciitis usually starts gradually with pain on standing after rest. Pain is usually located under the heel or to the inside of the heel. Pain is usually at its worst on standing first thing in the morning. The pain will begin to ease once you get moving. Pain in the early stages tends to occur after activity rather than during activity. As plantar fasciitis continues the pain can become more constant and can then start to affect the way you walk.


Causes

Plantar fasciitis can develop when your feet roll in too far as you take each step. This rolling in, known as over-pronation, can happen for many reasons. It can be due to excessive weight gain, pregnancy, quickly increasing physical activity, tight calf muscles, poor biomechanics or merely wearing unsupportive, flat footwear. When your feet over-pronate, your arches can collapse, putting strain on the tissues in the bottom of your foot.


Symptoms

Plantar fasciitis typically causes a stabbing pain in the bottom of your foot near the heel. The pain is usually worst with the first few steps after awakening, although it can also be triggered by long periods of standing or getting up from a seated position.


Diagnosis

A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose plantar fasciitis. Occasionally, further investigations such as an X-ray, ultrasound or MRI may be required to assist with diagnosis and assess the severity of the condition.


Non Surgical Treatment

There are several things you can do to self-treat your heel or arch pain. The first thing is to wear better shoes and consider adding arch supports or custom foot orthotics to your shoes. Stretching the calf muscles can also often be helpful. Try to stretch when you first get up in the morning and before you go to bed at night. Another good exercise is to “roll” your arch and heel. This is done by placing a tennis ball, golf ball, or lacrosse ball on the floor and rolling your foot on top of it. Some people get extra benefit by “rolling” on a frozen water bottle. You should also carefully evaluate your fitness program as you may be overdoing it. You may want consider backing of new or recently added exercises or increases in training until your heel pain improves. If you work at a standing job try to take more time to walk around during the day and avoid standing in one place for too long.

Foot Pain


Surgical Treatment

Surgery is not a common treatment for this condition. Approximately 5% of people with plantar fasciitis require surgery if non-surgical methods do not help to relieve pain within a year. The surgical procedure involves making an incision in the plantar fascia in order to decrease the tension of the ligament. Potential risks of this surgical procedure include irritation of the nerves around the heel, continued plantar fasciitis, heel or foot pain, infection, flattening of the arch, problems relating to the anesthetic.
