Found this site... You already know how painful corns can be

 A corn is compacted hard skin, hyperkeratosis which  forms a dense conical core deep into the skin's epidermis. It is the skin's  over the top psychological response to  stress. They can be painful and  troublesome. How can something so small be so painful? Painful on any pressure, painful in shoes, painful to walk on.

Understanding how and why we can get a corn, is to understand how we can stop them.  Unfortunately, most individuals have been tolerating, suffering with their corns for a long time, and they can actually get worse and debilitating. In some cases repeated treatments can actually over time make the corns worse. 

Quick fix, quick to return!

Corns can develop on any part of the foot whereby the skin is subject to high peaks of repetitive stress commonly on pronounced anatomical sites e.g toes, plantar metatarsal joints, heel, anywhere subject to:

• Friction
• Pressure
• Break in skin barrier 

Poor fitting footwear, tight hosiery, gait issues, anatomical changes in foot shape, arthritis, boney prominences, impaired sensation, aging, fat pad atrophy.

Smoking can make corns more painful!

Microscopic examination of corn biopsies can occasionally reveal fibrous scar tissue, with nerve and capillary involvement. This replaces the cushioning subcutaneous fat to make the corn ultra painful to any pressure. 

Intractable painful corns can be  termed neurovascular. Temporary relief can be offered with podiatry enucleation using a scalpel. For long term relief an advanced treatment option can be offered by specialist podiatrists trained in more advanced corn removal techniques. 

Yes, there are different types of foot corns:

• Hard corn (heloma durum) 
• Soft corn (heloma molle) - interdigital / between toes
• Seed corns (heloma mille) -multiple tiny corns imbedded in callus
• Subungual corn - under the nail
• Bursitic involving joint bursa
• Neurovascular 

Corns need to be differentiated from verrucas. Corns are generally  found on pressure points, whilst verrucae can appear anywhere.

Corns can have different presentations.

•  If untreated the compacted multiple layers of hyperkeratosis can become very pronounced (thick)
• Soft corns between toes can become macerated (soggy) 
• Corns can become inflammed with an underlying bursitis
• Corns can break down and become infected
• Corns cause limping and affect quality of life
