What Is Pain Under The Heel
Plantar Fasciitis is a chronic pain in the heel that can just appear from nowhere but it is actually a long standing mechanical condition caused by prolonged stress on your foot. In most cases Plantar Fasciitis is a common, but very treatable, mechanical condition of the foot and responds positively to orthotics. A heel pain caused by prolonged stress on a ligament like structure in the arch that is very important in weigh-bearing activities. The tissue becomes damaged and needs to be helped to repair in order for the pain to go or subside to a manageable level. Orthotics for your feet can achieve this necessary healing for pain relief. It can be very painful, and even debilitating for sufferers.
The cause of plantar fasciitis is poorly understood and is thought to likely have several contributing factors. The plantar fascia is a thick fibrous band of connective tissue that originates from the medial tubercle and anterior aspect of the heel bone. From there, the fascia extends along the sole of the foot before inserting at the base of the toes, and supports the arch of the foot. Originally, plantar fasciitis was believed to be an inflammatory condition of the plantar fascia. However, within the last decade, studies have observed microscopic anatomical changes indicating that plantar fasciitis is actually due to a non-inflammatory structural breakdown of the plantar fascia rather than an inflammatory process. Due to this shift in thought about the underlying mechanisms in plantar fasciitis, many in the academic community have stated the condition should be renamed plantar fasciosis. The structural breakdown of the plantar fascia is believed to be the result of repetitive microtrauma (small tears). Microscopic examination of the plantar fascia often shows myxomatous degeneration, connective tissue calcium deposits, and disorganized collagen fibers. Disruptions in the plantar fascia’s normal mechanical movement during standing and walking (known as the Windlass mechanism) are thought to contribute to the development of plantar fasciitis by placing excess strain on the calcaneal tuberosity.
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 GP or podiatrist (a healthcare professional who specialises in foot care) may be able to diagnose the cause of your heel pain by asking about your symptoms and examining your heel and foot. You will usually only need further tests if you have additional symptoms that suggest the cause of your heel pain is not inflammation, such as numbness or a tingling sensation in your foot, this could be a sign of nerve damage in your feet and legs (peripheral neuropathy) your foot feels hot and you have a high temperature (fever) of 38C (100.4F) or above - these could be signs of a bone infection, you have stiffness and swelling in your heel, this could be a sign of arthritis. Possible further tests may include blood tests, X-rays - where small doses of radiation are used to detect problems with your bones and tissues, a magnetic resonance imaging (MRI) scan or ultrasound scan, which are more detailed scans.
Non Surgical Treatment
Sometimes physical therapy modalities are helpful. The most frequently used modalities include ultrasound (high frequency sound vibrations that create a deep heat and reduce inflammation) and galvanic electrical stimulation ( a carefully applied intermittent muscular stimulation to the heel and calf that helps reduce pain and relax muscle spasm, which is a contributing factor to the pain). This treatment has been found most effective when given twice a week. Repeated taping and padding is sometimes used. The felt pads that will be strapped to your feet will compress after a few days and must be reapplied. While wearing them they should be kept dry, but may be removed the night before your next appointment. Resistant cases of heel pain caused by plantar fasciitis, heel spurs or cases of stress fracture of the calcaneus often need to be placed in a removable below knee cast boot. It is important to be aware of how your foot feels over this time period. If your foot is still uncomfortable without the strapping, but was more comfortable while wearing it, that is an indication that the treatment should help. Remember, what took many months or years to develop can not be eliminated in just a few days.
In very rare cases plantar fascia surgery is suggested, as a last resort. In this case the surgeon makes an incision into the ligament, partially cutting the plantar fascia to release it. If a heel spur is present, the surgeon will remove it. Plantar Fasciitis surgery should always be considered the last resort when all the conventional treatment methods have failed to succeed. Endoscopic plantar fasciotomy (EPF) is a form of surgery whereby two incisions are made around the heel and the ligament is being detached from the heel bone allowing the new ligament to develop in the same place. In some cases the surgeon may decide to remove the heel spur itself, if present. Just like any type of surgery, Plantar Fascia surgery comes with certain risks and side effects. For example, the arch of the foot may drop and become weak. Wearing an arch support after surgery is therefore recommended. Heel spur surgeries may also do some damage to veins and arteries of your foot that allow blood supply in the area. This will increase the time of recovery.
