Cryotherapy is the destruction of diseased tissue by extreme cold. 
Your podiatrist will remove any overlying callus and the probe will be held closely to the lesion. An application will last 10—15 seconds and may be a little uncomfortable. A second application may be used. 
Afterwards the treated area will be covered. This area MUST be kept dry for 24 hours. 
Any pain usually settles within 10 minutes.  
However sometimes it becomes painful again after a few hours and you may need to take paracetamol or aspirin (not Ibuprofen as you want the inflammation to work with your immune system). It is common to get swelling and weeping from the treated area and this may persist for a few days. 
You will need to return to your podiatrist after a few weeks to assess if another application is needed.
