  • Treatment

    Mild symptoms of hives usually need no treatment. You can take Antihistamines like Benadryl which blocks the release of histamine, the cause of hives. For severe attacks of hives you may need to go to the emergency room and get an injection of adrenaline.

    1. Apply cool compresses
    2. Sleep and work in a cool room
    3. Wear loose fitting clothing
    4. Take cool showers
    5. Minimize vigorous activity
    6. Take antihistamines

  • Quotes

    Hives form when a chemical called histamine is released by specialized cells known as mast cells. It is true that allergic reactions ultimately lead to the release of histamine, but other circumstances can result in the release of histamine, causing an outbreak of hives. Histamine acts by causing blood vessels to leak fluid into the nearby tissues. In the skin, small areas of swelling develop as a result of capillary (the smallest blood vessels) leakage. — MedicineNet
