Hello,
These symptoms are suggestive of
hives. The most likely triggers for acute urticaria(
hives) are allergies to pets,
horses, latex and foods, such as shellfish and nuts, bee or wasp stings, allergies to medicines, viral infections, dental and sinus infections, fungal infections, blood transfusions and vaccines.
Take some oral antihistaminics like Benadryl (cause drowsiness) or Claritin and apply calamine lotion as it helps in soothing the skin.
