The plantar fascia is a thickened fibrous aponeurosis that originates from the medial tubercle of the calcaneus and runs forward to form the longitudinal foot arch. The function of the plantar fascia is to provide static support of the longitudinal arch and dynamic shock absorption. Individuals with pes planus (low arches or flat feet) or pes cavus (high arches) are at increased risk for developing plantar fasciitis.
Inappropriate footwear is the No. 1 cause of plantar fasciosis. Footwear that possesses toe spring and a tapered toe box holds your big toe in an adducted and extended position. In this position, your abductor hallucis muscle-the muscle responsible for moving your big toe away from your foot’s midline-pulls on a foot structure called the flexor retinaculum and may restrict blood flow through your posterior tibial artery, the vessel that carries blood to the bottom of your foot. Tissues in the sole of your feet begin to degenerate as blood supply to this area is decreased. Other recognized causes of or contributors to this health problem include the following, calf muscle shortening, plantar fascia contracture, Obesity, rheumatoid arthritis, reactive arthritis, Psoriatic arthritis, Corticosteroid injections.
If you have Plantar Fasciitis, you will most likely feel a sharp pain under the ball of you heel and it will often give pain when standing after a period of rest. For example when you get out of bed in the mornings or after being sat down. Some patients describe this feeling as a stone bruise sensation, or a pebble in the shoe and at times the pain can be excruciating. Patients with Plantar Fasciitis can experience pain free periods whereby the think they are on the mend, only for the heel pain to come back aggressively when they appear to have done nothing wrong. If your plantar fasciitis came on very suddenly and the pain is relentless, then you may have Plantar Fascial Tears. We will be able to differentiate between these 2 conditions, sometimes with ultra sound imaging. The treatment for each of these conditions will need to be very different.
Your doctor will ask you about the kind of pain you’re having, when it occurs and how long you’ve had it. If you have pain in your heel when you stand up for the first time in the morning, you may have plantar fasciitis. Most people with plantar fasciitis say the pain is like a knife or a pin sticking into the bottom of the foot. After you’ve been standing for a while, the pain becomes more like a dull ache. If you sit down for any length of time, the sharp pain will come back when you stand up again.
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.
If you consider surgery, your original diagnosis should be confirmed by the surgeon first. In addition, supporting diagnostic evidence (such as nerve-conduction studies) should be gathered to rule out nerve entrapment, particularly of the first branch of the lateral plantar nerve and the medial plantar nerve. Blood tests should consist of an erythrocyte sedimentation rate (ESR), rheumatoid factor, human leukocyte antigen B27 (HLA-B27), and uric acid. It’s important to understand that surgical treatment of bone spurs rarely improves plantar fasciitis pain. And surgery for plantar fasciitis can cause secondary complications-a troubling condition known as lateral column syndrome.
It is not always possible to prevent heel pain, but there are measures you can take to help avoid further episodes. Healthy weight. Being overweight can place excess pressure and strain on your feet, particularly on your heels. This increases the risk of damaging your feet and heels. If you are overweight, losing weight and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet can be beneficial for your feet. You can calculate your body mass index (BMI) to find out whether you are a healthy weight for your height and build. To work out your BMI, divide your weight in kilograms by your height in metres squared. A BMI of less than 18.5 means that you are underweight, 18.5-24.9 means that your weight is healthy, 25-29 means that you are overweight, 30-40 means that you are obese, over 40 means that you are morbidly obese. You can also use the BMI healthy weight calculator to work out your BMI. Healthy feet. You should always wear footwear that is appropriate for your environment and day-to-day activities. Wearing high heels when you go out in the evening is unlikely to be harmful. However, wearing them all week at work may damage your feet, particularly if your job involves a lot of walking or standing. Ideally, you should wear shoes with laces and a low to moderate heel that supports and cushions your arches and heels. Avoid wearing shoes with no heels.
