I don't know if you've figured out what you have but if you have or do please email me at amercedes@aol.com .  I have the same thing it started a week ago and they itch and I'm like a five year old i can't help but pick lol and when i pick at them which is pretty hard cuz they are hard and have no  popping poing but i pick them and squeeze them and eventually a watery substance comes out but it doesn't ever stop and they scab over and i just get more.They start of almost like a pimple would but you can't pop it or make it go away.  I have seen 3 doctors they just put me on antibiotics and creams and say i dunno.
