Hopefully I don't need to say that blood and pus are never normal. They are signs of infection. Any new "lumps" on your body are never normal and should be evaluated by a medical professional for diagnosis and treatment. It may be nothing. It may be a cyst, or it may be something more serious. You need to go to a doctor. In person. No one is able to (or will) diagnose you online. You only have one body. Please contact a health professional immediately.
