If you have been sexually active, you need to be screened for STDs while the outbreak of bumps is occurring.

You should definitely see your doctor about this. When you do, make sure to ask him/her if it's possible that you have Hidradenitis suppurativa - Wikipedia, the free encyclopedia.

I've found that the cysts can be dried up by using tea tree oil. It's a natural substance available in health food stores. I dip a q-tip in the tea tree oil and dab it lightly on the cyst once a day after showering. I rarely have to do it more than once or twice and the cyst is usually gone within 24-48 hours.

But make sure you see your doctor about this!

Not sure see a doctor OK
