The condition you are describing may be urticaria
which is itchy red lumps and bumps on the skin with sometimes swelling of lips and tongue. It is due to histamine
release from mast cells that can be triggered by infections or sometimes idiopathic. The condition resolves on its own and antihistamines help in lessening the symptoms.
Do NOT scratch as physical urticaria is one entity that worsens on scratching.
Full blood count (to exclude infections), liver function & thyroid
function check is sometimes helpful.
Long-acting non-sedating antihistamines over 6 weeks to 3 months (if 6 weeks is not enough) such as Allegra (Fexofenadine
) 180mg/90mg and/or cetirizine
10mg at night is recommended.
