Itchy red mark on my daughter's leg

Hello,

My 16 yr old daughter has two parallel red marks (like being caned two times) on her lower leg.  She could not recall being bitten by insects.  They itch.  That happened once before, and they faded away quite quickly.  It was her second time.  Any idea, suggestions?

Hello,
From the symptoms and picture,they look like hives. Hives (medically known as urticaria) are red, itchy, raised areas of skin that appear in varying shapes and sizes. They have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours.


The mainstay of treatment of hives is antihistamine which may be necessary for prolonged periods (in excess of 6 weeks). Give her non-sedating antihistamines such as Cetirizine(Zyrtec) or Loratadine(Claritin) may be needed to get symptom relief. Sedating antihistamines such as Chlorphenamine(Benadryl) is used at night to get urticaria control. Short courses of oral cortisone or steroids are taken for short periods (one to three days) to settle more severe symptoms.
You may give Vitamin C along with the prescribed treatment. Vitamin C is a general anti-allergy supplement. It helps stabilize mast cells so they are less likely to release histamine.
I hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.Kind regards.
