1: Sort out the causes and triggers, and avoid them as much as you can. For example if you are suffering from heat induced urticaria, avoid hot temperature.
2: Avoid offending stimuli, allergens or foods that can cause allergies like eggs, nuts, wheat, dairy products etc. Remember, different people can be allergic to different foods. Food elimination technique can be helpful i.e. avoiding one type of food at one time and noting the results and then repeating with other types. This can be time consuming though!
3: Do not rub or unnecessarily touch the rashes, this can cause the rashes to blister and increase itching.
4: Consult a qualified doctor for timely diagnosis and treatment and choose medicines which do not have side effects e.g. herbal products.
