Just wanted to give my 2 cents worth to you and those who replied to your note. This was the same way my 'bumps' use to appear... it happened once or twice a year... and now is occuring almost constantly... I don't want to be an alarmist, but maybe you should ask your doctor if this could possibly be hidradenitis suppurativa... it sometimes take a long time to diagnose, but if these bumps start coming up under your arms, on your butt, breasts or other sweat producing area and start leaving scars that are purplish/reddish, then you may have HS. Dial soap helps HS, but there is no actual cure, early surgery has been helpful to some tho... I hope to God that this is not what you have, but if it turns out to be, there is a wonderful hidradenitis support group on yahoo... look @ the pics!
