4. Itching Skin
Itching, red skin is very common in the early-onset stages of an allergy attack, and it might be one of the first symptoms that an allergy attack is about to occur; pay special attention if you have eaten something that might have contained an allergen (like peanuts or shellfish) and you suddenly start to experience any of the symptoms mentioned in this article – including itching, swelling of any body part or area and a blocked nose.
In most cases, a steroidal cream prescribed by your doctor is enough to take care of the itching skin associated with an allergy attack: See your doctor if the condition persists, and mention to your doctor if you think that the condition might be caused by an allergy.
Allergic reactions can also come with just skin reactions, particularly if the allergen is something that has been applied to the skin – like if someone is allergic to the perfume used in their soap or to their detergent.
