If you feel you are suffering from allergies you should visit a doctor for a simple allergy test to get a proper diagnosis. Your doctor may suggest treatment medications such as antihistamines, anti-inflammatory creams, or even nasal sprays. Allergy shots may even be recommended for more persistent allergies. However, for random small skin problems due to allergies, simple remedies such as cold wet cloths or ice packs can work wonders to bring down the swelling and itchiness! These generally work as well for treatment and you can avoid the annoying side effects like drowsiness, that most prescription, and even over the counter, medications come with.
So next time you pat Fluffy the cat, or have an walk through the grass outside, and get a rash in return – grab a bag of frozen corn or peas from the freezer and mould it to the area you need to treat and watch the redness go down!
