Hi. It is important to note that there may be many causes to treatment failure : 1. Incorrect drug, dose and duration of therapy, 2. Some other close contacts harbouring the infection and thereby again spreading it to u 3. Organism may be resistant to the therapy which was prescribed, 4. Not maintaining proper hygiene... These are a few causes, of course u must see ur nearest dermatologist for optimum care and therapy.
