What should I do if the sole of my foot is bitten by a mosquito?

After being bitten by a mosquito on the sole of the foot, immediately rinse the affected area with clean water to remove the mosquito's saliva and any potentially attached bacteria. To relieve redness, swelling, and itching, apply a cold compress—for example, gently place an ice pack wrapped in a damp towel on the bite site, taking care to avoid direct contact between the ice and skin to prevent frostbite. If itching or swelling is significant, apply an anti-allergy ointment or anti-itch lotion, such as calamine lotion, to alleviate discomfort. Additionally, avoid scratching the bite to prevent worsening symptoms or secondary infection. If symptoms persist or worsen—such as increasing pain, fever, or signs of infection—seek medical attention promptly for professional evaluation and treatment. Meanwhile, take preventive measures against mosquitoes, such as using insect repellent or mosquito nets, to reduce the risk of future bites.
