Any chance you've changed laundry detergents or bath soap? This does sound like an allergic reaction to something, but to something you are coming in contact with...Are you swimming in a chlorinated pool or in water that could be contaminated with something? Are you eating honey or taking bee pollen supplements? Have you taken an antibiotic for something recently? There are two main "histamine" (allergic) responses...One is systemic (seen with full blown reactions where the patient has an all-over rash and/or difficulty breathing/ throat swelling, etc.) or a localized one where there is redness, swelling, and itching that will usually go away with little or no treatment. Each reaction is a single event so, no, this should not be related to a lasting bee sting from 3 weeks ago. There is something else causing the problem...~MM
Hello,
Hives are of two types:acute and chronic(when hives persist for more than 6 weeks). The most likely triggers for acute urticaria are allergies to pets, horses, latex and foods, such as shellfish and nuts,bee or wasp stings,allergies to medicines,Viral infections, such as glandular fever and herpes, dental and sinus infections, fungal infections, blood transfusions and vaccines.
In your case the bee sting can be responsible for these hives. The mainstay of treatment of hives is antihistamine which may be necessary for prolonged periods (in excess of 6 weeks). You can take antihistamines such as Cetirizine or Loratadine. Sedating antihistamines such as Chlorphenamine or Hydroxyzine are 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 take 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 regards.
