presents with Fever
, running nose, cough and red eyes.
Rash appears about 3 to 4 days after fever and it appears behind the ears first, then progresses to face, neck, trunk and limbs
. Its a red rash and no blisters are seen.
presents with blisters and the rashes are more on the trunk. Usually immunity after chicken pox is life long. So its unlikely that your kid has chicken pox.
If possible try to upload the picture of those rashes.
If rash persists/ spreads to other areas/ he develops fever etc its better that you see your Pediatrician
at the earliest.
Hope my answer helps you.
Wish your son good health.
