What Causes Red Rashes On Arm, Face And Legs?

My 2 yr old daughter has a light red rash on her arms, face, and legs. It s slightly elevated. She is not scratching the rash or complaining. She does not have a fever. It started on Saturday when I woke her up from her nap. She was sweating hot and I first noticed it on her arms. Should I take her to the doctor ASAP ? Advil and 1/2 tab of benedryl does not effect the rash.

hi, welcome to this forum. Can understand your concerns.
- Red rash on arms, legs and face in a 2 year old child can be due to measles, insect bite, viral infection, chicken pox or allergic reaction to drug.
- In insect bite, there is rash over exposed parts of body like legs, arms and face and fever is usually not present. There is itching which can start within 24 hours.
- In measles, there is rash over legs, arms and face and it is usually associated with fever. It also associated with itching.
- In chickenpox, there are fluid filled rash which occur simultaneously on all body parts. Fever is usually associated with chickenpox.
- Viral infection can also lead to rash over body, but this rash usually subside within 48 hours, and does not lead to any complications like itching.
- In drug allergy, there can be rash which appears simultaneously all over the body and results in intense itching.
From the history, chances of insect bite or viral infection seems to be quite high. However, an examination by doctor should be done so that we may not miss any important finding.
I hope this will help you. Wishing your child good health. Take care.
