Infracalcaneal bursitis is inflammation of a bursa-a fluid-filled sac-below your calcaneus, or heel bone. Bursae are situated in various locations throughout your body where friction between tissues commonly occurs, and these sacs are designed to help reduce this friction and prevent pain. Repetitive movements or prolonged and excessive pressure are the most common causes of bursal inflammation, though traumatic injury may also cause this painful problem. Indeed, your body sometimes creates bursal sacs in response to trauma or tissue damage. Infracalcaneal bursitis can sometimes be difficult to differentiate from plantar fasciosis-another condition that causes pain below the heel. The key difference is that infracalcaneal bursitis tends to be worse at the end of the day whereas plantar fascia pain tends to be worse in the morning, immediately upon waking.
Inflammation of the calcaneal bursae is most commonly caused by repetitive overuse and cumulative trauma, as seen in runners wearing tight-fitting shoes. Such bursitis may also be associated with conditions such as gout, rheumatoid arthritis, and seronegative spondyloarthropathies. In some cases, subtendinous calcaneal bursitis is caused by bursal impingement between the Achilles tendon and an excessively prominent posterior superior aspect of a calcaneus that has been affected by Haglund deformity. With Haglund disease, impingement occurs during ankle dorsiflexion.
A dull ache under the heel when not weight bearing. Sometimes severe pain when walking. Pain can increase after resting (sleeping or sitting) then standing and placing pressure on the area again. Throbbing under the heel. Swelling may be identified as a discernible lump under the heel. This is the swollen calcaneal bursa itself. Tingling under the heel as swelling affect the plantar nerves. Pains shooting into the foot or up the leg.
Like all other forms of bursitis, initially the physician will take down the history of symptoms experienced by the patient, this will be followed by a detailed physical examination which involves checking for inflammation signs like pain, redness, and warmth of the heel area. The physician might examine further by moving the ankle a little to determine the exact location of pain. Further diagnostic tests including x-ray, bone scans, and MRI scan might be suggested if required.
Non Surgical Treatment
Most bursitis cases can be treated by the patient without having to see a doctor. A trip to a pharmacy, a conversation with the pharmacist, and some self-care techniques are usually enough. The NHS (National Health Service, UK) recommends PRICEM, a self-care management approach. PRICEM stands for Protection. Rest. Ice. Compression. Elevation. Medication. Protect the affected area, Some people place padding to protect the affected bursae from any blow. Rest. Do not exercise or use the joints in the affected area unless you really have to. Let it rest. Bursitis is a condition that responds well to rest. Ice packs. Ice packs can help reduce pain and inflammation. Make sure you do not place the ice directly on the skin, use a pack or towel. A small pack of frozen vegetables are ideal. Raise the affected area. If you can, lift the affected area, raise it, less blood will gather there. This may help reduce the inflammation. Painkillers. Ibuprofen is an effective painkiller for treating pain, it also reduces inflammation. Steroids. For more severe symptoms the doctor may inject steroids into the affected area. Steroids block a body chemical called prostaglandin. Prostaglandin causes inflammation. Steroids may raise the patient’s blood pressure if used for too long, as well as increasing his/her risk of getting an infection. UK doctors are advised not to give more than three steroid injections in one year. Antibiotics. If the fluid test confirms that there is a bacterial infection, the doctor will probably prescribe antibiotics. These will be administered orally (via mouth).
Bursectomy is a surgical procedure used to remove an inflamed or infected bursa, which is a fluid-filled sac that reduces friction between tissues of the body. Because retrocalcaneal bursitis can cause chronic inflammation, pain and discomfort, bursectomy may be used as a treatment for the condition when it is persistent and cannot be relived with other treatments. During this procedure, a surgeon makes small incisions so that a camera may be inserted into the joint. This camera is called an arthroscope. Another small incision is made so that surgical instruments can be inserted to remove the inflamed bursa.
