Hello and hope you are doing well.
Normally, during the course of evolution from a baby to an adult, we develop a mechanism by which we desensitize ourselves to all the materials we are exposed to. But sometimes, the desensitization may not be perfect and we develop allergic reactions to those few substances. This is what happened in your case. On exposure to the allergen, an Immunologic (IgE) or a non-immunologic reaction is set in process, which ultimately releases histamine, which acts at the peripheral receptors, resulting in allergic reactions and rashes.
The aim of the therapy is identification and removal of trigger factor. It is the most important and the only effective long-term therapy.
Local measures like ice packs and antipruritic lotions are helpful. Antihistamines block the histamine receptors and prevent histamine from acting and thus help in preventing rashes. Consult an allergy specialist. In the meantime take OTC antihistamines.
Hope this helped and do keep us posted.
