Understanding the cause of the allergic reaction is very important to enable avoidance and, if necessary, treatment. In the UK there are several support groups / associations such as Allergy UK who can offer help and support on various allergy topics. Also refer to this website's Top Tips and the Minimising Attacks section to help you with avoidance where possible.

There are also asthma and eczema associations often working locally so ask your pharmacist or doctor for those that work in your area.
