Unexplained rashes are one of the main reasons that people go to see a dermatologist. There are so many different types that can be caused by a variety of things, ranging from allergies to viral infections. They can be small or cover large sections of the body and be different shades of purple, red or brown. They are often itchy or uncomfortable, and can cause blistering, bumps and lesions on the skin.
The reason that many people panic when they develop a rash is that it can be caused by a multitude of things and speak to your overall health. They are generally triggered by:
- An allergic reaction to food, medication or something in the environment
- An undiagnosed skin disorder
- An infection or disease
Most rashes, however, are not a cause for major concern and can be managed with antihistamines or lotions containing cortisone.
Some of the most common rashes include:
- Hives (urticaria)
- Contact dermatitis (allergies)
- Skin disorders, such as eczema, psoriasis and rosacea
- Heat rash
- Viral infections, such as measles and chickenpox
Many disappear on their own after a few days but ones that become worse or persist should be examined by a doctor to get an accurate diagnosis. Once the cause has been established, a proper treatment plan can be put in place to restore the skin and body for optimal wellbeing.
If a rash appears suddenly, spreads all over your body or is accompanied by a fever, make sure that you seek out medical treatment.
