Skin allergies are very common, and their main symptoms include itching, rashes, or changes in skin color. One of the more common symptoms of skin allergies is itching, which in some patients may be so severe that it makes it hard to sleep. Another symptom is developing rashes. It is important not to scratch the rashes with hands, as breaking the skin can lead to secondary bacterial infections.

What should I do if I have an allergic reaction to a wasp sting?

After being stung by a wasp and experiencing allergic reactions, the first step is to treat the sting site. You can wash the wound with soap and water or an alkaline solution to reduce the absorption of toxins. Additionally, thoroughly disinfect with iodine. Also, inspect the sting site for any remaining stinger; if present, remove it to decrease further toxin absorption and alleviate symptoms. For skin allergies, oral antihistamines such as levocetirizine or loratadine can be taken to ease symptoms. If the allergic skin reaction is severe and covers a large area, and oral medications are ineffective, intravenous administration of antihistamines such as dexamethasone, calcium gluconate, and high doses of vitamin C can be considered for treatment to relieve symptoms. It is also important to watch your diet and avoid spicy, irritating foods and seafood. (Please follow medical advice regarding medication use.)

What should I do if I have skin allergies and itching?

Skin allergies and itching require actively searching for the triggering factors, i.e., allergens. Identifying what has irritated the skin and caused the allergic reaction is crucial, then avoiding further contact to prevent recurrence or worsening of the condition. If the allergy is triggered by consuming fish, shrimp, seafood, tropical fruits, etc., it is important to avoid eating similar foods in the future. If the use of certain cosmetics or skin care products causes allergies, avoid using other products containing the same ingredients. If the allergy is caused by certain medications, typically appearing within four days to a month of usage, it is advised to switch medications and avoid taking the same one again. For more severe allergic symptoms, such as significant itching, oral antihistamines like loratadine, desloratadine, cetirizine, and ebastine can be taken. Topical anti-itch medications like calamine lotion can be used, and for more severe conditions, topical corticosteroids or tacrolimus ointment can be applied. If symptoms do not improve or worsen with the aforementioned treatments, short-term oral steroids might be considered to manage the condition. (Note: Medication should be used under the guidance of a physician.)

Can you eat eggs if you have a skin allergy?

Eating eggs in case of skin allergies depends on the situation. If you have never been allergic to eggs and have been consuming them, then you can still eat eggs even if you have a skin allergy. Eggs are considered neutrally balanced and sweet, containing almost all the nutrients required by the human body, thus they are often referred to as ideal nutrient stores. Traditional Chinese medicine believes that eggs have the effects of nourishing yin and moistening dryness, as well as nourishing blood and stabilizing pregnancy. Clinically, egg allergies are more commonly seen in infants and toddlers. Therefore, if you have never eaten eggs before, or if you have been diagnosed with an egg allergy through an allergen test, you should not eat eggs when you have a skin allergy.
