If you have any flea shampoo, give her a bath. She needs to get rid of the fleas. Make sure you put some mineral oil in her eyes to protect them from the shampoo. Don't use human shampoo since it isn't made for their skin and can irritate it more. Also make an appointment with your vet, her eyes may have an infection in them which can cause some of the discharge. Have her ears checked also since they may also be infected and can definitely cause her some pain and distress.
