the smoke could definitely be the culprit especially if one of the woods being burned in the campfire was one she's allergic to.
hives due to campfire smoke exposure. my 4 year old has had hives on her face and left eyelid one hand and stomach area for 3 days now. we are giving her oral benadryl liquid putting hydrocortisone on the lower half of her face hand and stomach. cool baths and compresses. nothing she has been in contact with has changed. we have not changed her diet soap etc. the only thing i can think of that is different is that she was exposed to campfire smoke 4 days ago. could the smoke cause the hives?
