How to quickly reduce swelling and relieve pain from a bite by horseflies or other biting insects

After being bitten by horseflies or other biting insects, the following methods can help quickly reduce swelling and relieve pain: 1. Cold compress: The saliva of horseflies contains toxins and allergenic substances that can cause redness, swelling, and pain after a bite. At this time, applying a cold compress with an ice pack wrapped in a towel or using gauze soaked in diluted zinc oxide solution for 10–20 minutes can help alleviate swelling and pain. 2. Proper medication: If symptoms are severe, antiallergic medications such as antihistamines (e.g., diphenhydramine, cetirizine) may be used according to medical advice to reduce vascular permeability and alleviate swelling. Additionally, corticosteroids such as mometasone furoate cream or hydrocortisone cream also have good anti-inflammatory and swelling-reducing effects and may be applied locally as directed by a physician. 3. Removing venom: If local swelling and pain are very severe, a healthcare professional may use a vacuum device to extract the venom, thereby reducing irritation from the venom and accelerating the resolution of swelling and wound healing. 4. Keeping the area clean and dry: During recovery, it is important to keep the affected area clean and dry to avoid contact with water and prevent infection. Additionally, maintain a light diet and avoid spicy, greasy, or other irritating foods that may worsen swelling and pain. If severe discomfort or an allergic reaction occurs after being bitten, seek medical attention promptly.
