I have bumps that form on my vagina sometimes. The bumps are really big sometimes. When I pop them liquid puss nd blood come out. Is this normal?

No-need eval. This is not normal to have theses bumps form. You need eval by your doctor. These could be carbuncles and ultimately if frequent and numerous this could be a condition called hydradenitis suppurativa. Other conditions are herpes or chancroid if you are sexually active. Please sched appoint to see your doctor.
