USA HISTORY

Detailed explanation-1: -Trench foot is a condition you can develop if you stand in a cold, wet environment for an extended period of time. Symptoms of trench foot include numbness, pain, redness and swelling. Trench foot occurs when cold temperatures and moisture combine, causing restricted blood flow to your foot.

Detailed explanation-2: -Trench foot is caused by prolonged exposure to a cold temperature that is usually above freezing and damp, sometimes unsanitary conditions. The condition ultimately causes skin and tissue breakdown which increases the risk of infection and increases associated morbidity and mortality.

Detailed explanation-3: -Trench foot, also known as immersion foot, occurs when the feet are wet for long periods of time. It can be quite painful, but it can be prevented and treated.

Detailed explanation-4: -Stage 4-Post-Hyperaemic Phase This is a long-term vasospastic (narrowing of the blood vessels) phase involving increased pain on warming, hyperhidrosis (extreme and excessive sweating) of the feet, and paresthesia (pins and needles sensation). The affected foot/feet may develop a sensation of being cold, permanently.

Detailed explanation-5: -Once the foot warms up, people may notice their foot changes from white to red, eventually becoming dry and painful. Blisters can form, leading to skin and tissue falling off the injured foot. If trench foot is left untreated, it can lead to gangrene and even the need for amputation.
