No insurance supposed to get another mastoidectomy but in my l ear cuz it drains const. but i'm getting blood when it drains what can i do at home?

Mastoiditis: You have a serious infection and you should follow the doctors advice and go through mastoidectomy and you will need antibiotics, dont ignore and see your ENT specialist and dont play around with it.

See a doctor: I highly advised that you see a professional to get evaluated and treated. Please do not try to treat yourself at home.
