Canker rash refers to a skin condition that is characterized by the presence of inflamed and irritated sores or ulcers on the skin. These sores are usually painful and may be accompanied by redness, swelling, and tenderness in the affected area. The term "canker rash" is commonly used to describe mouth ulcers or sores that develop on the mucous membranes inside the mouth, such as the gums, inner cheeks, and tongue.
Canker rash is often associated with viral infections, such as the herpes simplex virus or the coxsackie virus, although it can also be caused by other factors. These may include trauma or injury to the mouth, hormonal changes, nutritional deficiencies, stress, or a weakened immune system.
The exact cause of canker rash is not fully understood, but it is believed to involve a combination of genetic, environmental, and immunological factors. The condition is not contagious and typically resolves on its own within one to two weeks. However, the discomfort and pain associated with canker rash can be managed with over-the-counter topical treatments, oral analgesics, or prescription medications, as recommended by a healthcare professional. It is important to maintain good oral hygiene and avoid irritants, such as spicy or acidic foods, which can further aggravate the condition. If symptoms persist or worsen, it is advisable to seek medical attention for a proper diagnosis and appropriate treatment.
