How is heat rash diagnosed?
Heat rash can usually be identified by its appearance and does not usually require medical attention. However, if doesn’t go away after 3 or 4 days, or if it appears to be getting worse, or if your child develops a fever, contact your health professional right away. When you or your child has a rash, it is important to watch for signs of infection, including: • Increased pain, swelling, redness, or warmth around the affected area. • Red streaks extending from the affected area. • Drainage of pus from the area. • Swollen lymph nodes in the neck, armpit, or groin. • Fever of 100 °F (37.8 °C) or higher, or chills with no other known cause. If any of these symptoms develop, contact your health professional immediately.
