Fleas inject their saliva into your skin; the saliva has anesthetic properties so you don't feel the bite at first. After being bitten, you'll discover small red bumps on your skin that will itch and may hurt. Flea bites usually heal on their own in about a few days, unless they're so itchy that you can't help but scratch them. Scratching fleabites can cause more swelling and damage the skin, exposing it to microorganisms that can cause infections. If you have flea bites on your legs, there are ways to reduce the swelling, relieve the itching and speed up the recovery time so that they'll quickly disappear.
Resist the urge to scratch your legs. Scratching the bites may worsen the pain and discomfort.
Wash your legs with antibacterial soap and water. This will lessen the risk of infection.
Wrap an ice pack or a cup of ice cubes in a clean towel. Apply it directly to the bitten areas, which will help soothe the itchiness.
Apply a skin ointment or cream made for insect bites. There are many creams to choose from -- camphor, menthol or calamine, for example -- so ask the pharmacist to help you choose the best one for fleabites.
Apply an over-the-counter ointment, cream or scrub that reduces pain and prevents blistering and scarring from insect bites. Again, ask the pharmacist to help you choose the best one for flea bites.
Read the directions of the creams or ointments thoroughly before applying to your skin. Consult your physician immediately if you develop fever, headaches, body aches or rashes or have difficulty breathing. It's possible that you may be allergic to flea bites. Fleas can also transmit diseases such as typhus, plague and bartenellosis.
