Hives: It sounds as if you are having a dermatologic condition called urticaria. Urticaria is the medical terminology for hives. It is the bodies response to a certain stimulus, such as an allergy. The body will release histamine in response to a stimulus and histamine causes redness, swelling and itching. Other triggers of urticaria can be cold/heat, stress, medicines, or with you, pressure on skin!

If it disappears: Completely overnight, you are probably reacting to something that you consume or come in contact with before you go to bed. You can try antihistamines such as Diphenhydramine otc. If it persists, consult a dermatologist.
