If it was a while ago,
perhaps you should ask your doctor for a referral
to your allergist if
that is necessary.
In Canada, that is the protocol. One can develop
new allergies. Also ask yourself if you have introduced any new products
into your environment such as a new laundry detergent, new soaps,
shampoos, body lotions etc. You may need a referral to a dermatologist
as this also sounds like a skin issue. Good luck to you.
