ND11.9/S90 Nonthermal blister of other or unspecified parts of foot



Nonthermal blister of the feet is caused by a combination of friction and shear forces, resulting from repetitive activities such as running or walking. This can be exacerbated by ill-fitting shoes or socks.


The diagnosis of nonthermal blister of the feet is usually made based on the patient’s history and physical examination. It is important to look for signs of infection, such as redness, swelling, and drainage.

Differential diagnosis

Differential diagnoses include thermal burns, contact dermatitis, and infective cellulitis.


Treatment consists of rest, elevation of the affected area, and protection from further friction. Topical anesthetics may be used to reduce pain. Antibiotic ointments may be prescribed to prevent infection.


The prognosis for nonthermal blister of the feet is generally good, with most cases resolving within a few days to weeks. Surgery may be needed in more severe cases.
