Skin Rash First Aid

Most common rashes are a result of contact dermatitis like poison oak, ivy or sumac or allergic skin reactions to environmental substances. Allergic reactions to "unknown" substances may require testing and treatment by a dermatologist. Rashes may also by symptoms of other medical conditions like acne, shingles, psoriasis, lupus, or cellulites. Determining the origin of the skin irritation or symptom is important. Try to "rule out" potential reasons for the rash. Review activities or event within the last 48-72 hours. Consider suspect plants, detergents or other substances that were newly introduced before the rash irrupted. If pre-existing medical conditions exist, determine if rashes are a symptom. If concerned see medical advice or attention. To treat skin rash see Rash Treatment. More Information
