Since both of you like developed similar symptoms , it looks like you both have developed vector dermatitis
This is basically a type of allergic reaction
which develops due to crawling of an insect over the skin.
This mostly is seen over the exposed areas of the body.
It causes an allergic reaction which mostly develop overnight.
You need to use a topical steroid
over the affected area.
Take oral antihistamines to bring down the allergy
Hope it helps
