“Rash” is a general term for a wide variety of skin conditions. A rash refers to a change that affects the skin and usually appears as a red patch or small bumps or blisters on the skin. Certain genes can make people more likely to get rashes.
Some rashes develop right away. Others form over several days. Although most rashes clear up fairly quickly, others are long-lasting and need long-term treatment.
Because rashes can be caused by many different things, it’s important to figure out what kind you have before you treat it. If it is a bad rash, if it does not go away, or if you have other symptoms, you should see your dermatologist. The majority of rashes are harmless and can be treated effectively with over-the-counter anti-itch creams, antihistamines and moisturizing lotions.
Rashes can be a symptom for other skin problems. The most prevalent of these are:
- Atopic Dermatitis, the most common form of eczema.
- Bacterial Infections, such as impetigo.
- Contact Dermatitis, a type of eczema caused by coming into contact with an allergen.
- Chronic skin problems, such as acne, psoriasis or seborrheic dermatitis.
- Fungal Infections, such as ringworm and yeast infection.
- Viral Infections, such as shingles.
A rash may be a sign of a more serious illness, such as Lyme Disease, Rocky Mountain Spotted Fever, liver disease, kidney disease or some types of cancers. If you experience a rash that does not go away on its own after a few weeks, make an appointment to see one of our dermatologists to have it properly diagnosed and treated.
