The bumps which I understand from history are a form of acne, that normally happens with oily skin, clogged pores or not having a good diet. You need to stop putting oil on those and start with an antibiotic cream. Oiling your hair is only recommended half hour before taking a shower on normal days not right now. And using a mild antidandruff shampoo is recommended. Rest your face needed to be examined for the kind of face wash which is needed for your skin.
