What are skin rashes?
A rash is a skin condition in which a patch of skin becomes swollen, irritated, itchy, or red. Skin rashes can occur very suddenly or develop over time and can occur all across the body. Many different conditions and external factors can trigger a rash, so the treatment for a rash depends on what is the underlying cause of the rash.
Some people experience rashes as an allergic reaction to a food, medicine, substance, or other irritant while others develop rashes as a result of dry skin. One of the main causes of a skin rash is contact dermatitis, which is your skin’s immediate reaction to an allergen. No matter the cause, most rashes clear up relatively quickly though some require longer-term treatment. Rashes are very common and not usually cause for concern unless accompanied by other symptoms.
