Trench foot (immersion foot)

About Trench foot (immersion foot)

Occurs when the feet are wet for long periods of time. It is more common when a person has been standing or sitting, and the feet therefore are lower than the heart (dependent). It also is more common if the shoes are too tight. The temperature does not have to be cold for this to occur. It can be quite painful, but it can be prevented and treated. Trench foot also is known as immersion foot.

Symptoms

Initially patients experience tingling and/or itching sensation, pain, swelling, cold and blotchy skin, numbness, and a prickly or heavy feeling in the foot. Later the foot may be red, swollen, and painful. Blisters and skin death can occur.

Tests & Diagnostics

A history and physical exam will be done. Tests to determine the extent of the damage may be performed.

Common tests: X-ray.

Conventional treatment summary

The feet will be thoroughly cleaned and dried. If the feet were in cold water rewarming should be done by soaking in warm water (104 to 108 degrees Fahrenheit) for approximately 5 minutes. In the hospital the feet will be examined for any associated infection or frostbite. Further treatment depends on the severity of the condition.
