When I fell asleep in bed, I was itchy and felt like a bug was biting me.

I feel itchy when I fall asleep in bed, and I feel like I've been bitten by a bug for the following reasons:

1, mosquito bites: The itching and little red dot after mosquito bites can be washed with soapy water, and the severe itching can be washed with calamine lotion and mosquito repellent.

2, skin allergies: skin itching and redness after contact with allergens can be treated with oral antihistamines.

3. Mite infection: there is mite infection in the room, so you need to clean your body with sulfur soap, iron pillowcases and sheets with boiling water, and expose yourself to the sun.
