Infracalcaneal bursitis (inflammation of the bursa below the calcaneus, or heel bone) is one of the most common types of bursitis in the foot. 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.
As ligaments and tendons stretch and tear, blood from ruptured blood vessels becomes trapped in the local tissues. As the trapped blood clots up, it sticks the tissues together creating adhesions. Adhesions cause pain, inflammation and restricted movement because the layers of tissue that used to slide smoothly across one another now adhere and snap which interferes with normal functioning. It is essential to break up clotted blood as quickly as possible to prevent adhesions and scar tissue from forming.
Pain and tenderness usually develop slowly over time. Applying pressure to the back of the heel can cause pain. Wearing shoes may become uncomfortable. The back of the heel may feel achy. Pain is exacerbated when the foot is pointed or flexed, because the swollen bursa can get squeezed. A person with retrocalcaneal bursitis may feel pain when standing on their toes. Fever or chills in addition to other bursitis symptoms can be a sign of septic bursitis. Though uncommon, septic retrocalcaneal bursitis is a serious condition, and patients should seek medical care to ensure the infection does not spread.
Your GP or therapist will be able to diagnose you by both listening to your history and examining you. No X-rays or further investigation should be needed to confirm diagnosis but may be requested to check for any underlying health conditions that may have triggered the bursitis.
Non Surgical Treatment
You should rest from all activities that cause pain or limping. Use crutches/cane until you can walk without pain or limping. Ice. Place a plastic bag with ice on the foot for 15-20 minutes, 3-5 times a day for the first 24-72 hours. Leave the ice off at least 1 1/2 hours between applications. Compression. Lightly wrap an elastic bandage from the toes to mid calf, using even pressure. Wear this until swelling decreases. Loosen the wrap if your toes start to turn blue or feel cold. Elevate. Make sure to elevate the ankle above heart level. To improve symptoms of plantar calcaneal bursitis after the acute phasetry the baked bean tin stretch, using a baked bean tin roll the foot backwards and forwards. 2 minutes in the morning before putting the foot to the floor. 5-10 minutes every evening. Contrast foot baths. 10 minutes warm water. 10 minutes cool water morning and evening (morning may be missed if time is restricted). Stretches. Start with 10 stretches per day, holding the stretch for 30 seconds, then relax and then repeat. Continue this stretch daily until you can no longer feel it pulling on the heel, then progress to stretch. Do 10 per day holding for 30 seconds per stretch. When you can no longer feel it pulling on the heel proceed to stretches. Do 10 per day holding for 30 seconds on every stretch.
Only if non-surgical attempts at treatment fail, will it make sense to consider surgery. Surgery for retrocalcanel bursitis can include many different procedures. Some of these include removal of the bursa, removing any excess bone at the back of the heel (calcaneal exostectomy), and occasionally detachment and re-attachment of the Achilles tendon. If the foot structure and shape of the heel bone is a primary cause of the bursitis, surgery to re-align the heel bone (calcaneal osteotomy) may be considered. Regardless of which exact surgery is planned, the goal is always to decrease pain and correct the deformity. The idea is to get you back to the activities that you really enjoy. Your foot and ankle surgeon will determine the exact surgical procedure that is most likely to correct the problem in your case. But if you have to have surgery, you can work together to develop a plan that will help assure success.
To prevent bursitis of the heel in the first place, always keep proper form during exercise. In addition, don?t jump into exercises that are too intense without building up to them. Strengthen and flex your ankle.
