Why do flea bites take ages to heal and why do they keep bleeding when i get out of shower or bath ? help

FLEA BITES: Flea bites maybe small lesion to big ulcers due to sucking of blood mostly on legs and feet.It may cause allergy reactions or infections.See your md for further evaluation and treatment.

Define "ages".: Insect bites do take awhile to heal, but my guess is that you are scratching them, whether you are aware of it or not, and that is causing the bleeding and delaying healing. Try covering them with bandaids and change them daily, after your shower. If they still persist, something else may be going on and you should see your doctor.
