In spring, there are many substances that can cause allergies in people, such as pollen, dust mites, and plant fibers. For individuals with excessive sensitivity, their immune response sensitivity exceeds the appropriate level and scope. They may perceive harmless foreign substances, such as certain pollens and proteins, as invaders and neutralize or digest them (usually resulting in itching, redness, hives, swelling, and other allergic reactions). This can harm normal cells, tissues, and organs in the body, leading to localized or systemic allergic reactions.
Common spring allergy symptoms include hay fever (allergic rhinitis): frequent sneezing, itchy and watery eyes, itching in the back of the throat or upper palate; allergic asthma: sneezing, wheezing, coughing, and some individuals may experience difficulty breathing; food allergies: skin redness, itching, swelling, and discomfort in the stomach; medication allergies: skin redness, itching, swelling, and sometimes symptoms similar to the common cold, such as headache, mild fever, and joint pain.
When many people realize they have skin allergies, they often buy ointments from pharmacies and apply them by themselves. This should be avoided because most topical medications contain hormones. If used on the face, it can cause corticosteroid-induced dermatitis. The symptoms may quickly improve in the short term after using the medication, but worsen after discontinuation. Prolonged use can lead to drug dependence, causing the skin to become rough, atrophic, and the rashes more severe. Treating such conditions becomes more difficult and challenging. It is best to visit a reputable hospital for patch testing to determine the allergen and receive targeted treatment under the guidance of a doctor. It is also beneficial for making lifestyle choices to minimize exposure to allergens in the future.
