Pain under the heel is a common symptom. It can occur without explanation. Often the pain becomes worse with increasing weight. A typical feature of a heel spur is that it is initially really painful after rest. The cause of the condition is an inflammation of the tendon junction in the sole of the foot. On the X-ray a bone spur can sometimes be seen right where the inflammation is located.
There are many treatments for heel spurs, but none of them are so good that the problem goes away for sure. Usually we begin with a heel insole to reduce pressure to the heel fat pad. Anti-inflammatory tablets can also be tried. Cortisone spray is a common treatment but this is not entirely risk-free. Recently, treatment with extracorporeal shockwave therapy has been tried, but it is painful and relatively ineffective.
Most heel spurs heal within 6 months. A few, however, result in chronic inflammation that is difficult to treat. Tape therapy is worth trying in these cases. The tape is attached directly to the skin and provides considerable stability. However, it slowly slides off and must be taped on every week. After 4-5 weeks, the skin can no longer tolerate the tape, and the treatment has to be terminated. You can not apply the tape yourself, and you have to get assistance with a referral to a physiotherapist.
Many people do so well after taping that they can resume exercising even if the symptoms do not completely disappear. Chronic inflammation also eventually heals even though it may take a long time, sometimes years.
