Most warts are harmless, even though they may be painful. They are often mistaken for corns or calluses, which are layers of dead skin that build up to protect an area which is being continuously irritated. The wart, however, is a viral infection.
Plantar warts tend to be hard and flat, with a rough surface and well-defined boundaries; warts are generally raised and fleshier when they appear on the top of the foot or on the toes. Plantar warts are often gray or brown (but the colour may vary), with a centre that appears as one or more pinpoints of black. It is important to note that warts can be very resistant to treatment and have a tendency to reoccur.
When plantar warts develop on the weight-bearing areas of the foot (the ball of the foot, or the heel, for example), they can be the source of sharp, burning pain. Pain occurs when weight is brought to bear directly on the wart, although pressure on the side of a wart can create equally intense pain.
Self-treatment is generally not advisable. Over-the-counter preparations contain acids or chemicals that destroy skin cells, and it takes an expert to destroy abnormal skin cells (warts) without also destroying surrounding healthy tissue. Self-treatment with such medications especially should be avoided by people with diabetes and those with cardiovascular or circulatory disorders. Never use these medications in the presence of an active infection.
When to Visit a Podiatrist
It is wise to consult podiatrist when any suspicious growth or eruption is detected on the skin of the foot in order to ensure a correct diagnosis. It is possible for a variety of more serious lesions to appear on the foot, including malignant lesions such as carcinomas and melanomas. Although rare, these conditions can sometimes be misidentified as a wart.
Diagnosis and Treatment
It is possible that your podiatrist will prescribe and supervise your use of a wart-removal preparation. More likely, however, removal of warts by a simple hyfrication procedure, performed under local anaesthetic, may be indicated. Liquid nitrogen may often be used depending on the size and position of the wart. The podiatrists at the footinjuryclinic are in a unique position as we have hyfrecation equipment which gives us more options when treating stubborn warts.
