Blister (nonthermal) of left upper arm, sequela

Blister (nonthermal) of the left upper arm, sequela, refers to a blister that has developed on the left upper arm as a result of a previous injury or condition. This sequela can be caused by various factors, including burns, insect bites, allergic reactions, or skin infections.

A blister is a small pocket of fluid that forms beneath the upper layers of the skin. It acts as a protective barrier against further damage and allows the skin to heal. In the case of a nonthermal blister, it means that the blister was not caused by heat or extreme temperatures.

Common symptoms of a nonthermal blister on the left upper arm may include redness, swelling, pain, and a raised bubble-like appearance on the skin. The size and severity of the blister can vary depending on the underlying cause and the individual's immune response.

1. Burns: A burn on the left upper arm can lead to the formation of a nonthermal blister. This can occur due to contact with hot objects, chemicals, or exposure to excessive sunlight.
2. Insect bites: Insect bites, such as those from mosquitoes or spiders, can cause an allergic reaction in some individuals, leading to the development of blisters.
3. Allergic reactions: Certain substances or medications can trigger an allergic reaction, resulting in blisters on the left upper arm.
4. Skin infections: Bacterial, viral, or fungal infections can cause inflammation and blister formation on the skin, including the left upper arm.

It is important to note that a nonthermal blister on the left upper arm may require medical attention to determine the underlying cause and appropriate treatment. Seeking professional advice is crucial for an accurate diagnosis and to prevent further complications.
