Allergic reactions occur when the body's immune system reacts abnormally to a drug, food, or other substance called an allergen. While some allergic reactions require immediate medical attention, minor allergic rashes can often be treated at home -- and typically resolve within a few days.

Ringworm, or tinea infection, is a general term used to describe a group of common infections caused by several different types of fungus. These infections can occur on your body, scalp, beard, groin or on your feet or toes, where the condition is commonly known as athlete’s foot.

Just hearing the word "ringworm” may make your skin crawl, but finding this fungal infection on your inner thighs is even more uncomfortable. Exercise can make ringworm worse, but it doesn’t necessarily have to interrupt your workout routine.

The severity of a scar often depends on how deep the initial wound penetrates. A scar is made from skin cells and connective tissues called fibroblast cells which use gristle like fibers to hold the wound together, notes American Osteopathic College of Dermatology.

A common fungal family called dermatophytes causes ringworm. The fungus can infect any area of the body where there is skin, hair or nails, and the infection is named for the part of the body that it infects. The parasites do not need light to survive, unlike “green” plants.

After contracting the virus that causes chicken pox, an individual can later develop herpes zoster, also known as shingles.

Bacteria and fungi are everywhere, but sometimes they set up shop on the skin and cause a rash. Warm, moist areas -- like under the breasts -- are more prone to these skin rashes than other areas of the body.
