Little lumps on your cervix are completely normal. They are called nabothian cysts and most women have them. They may go away on their own, or change size, but generally they're there forever. Nothing to worry about - but definitely don't poke and prod at them ;o)
Soory to hear about your ER visit. I avoid that place like crazy, they just get you in and out and tell you to see your regular Dr., but you were advised to go there so I can see why you are so upset. I have never checked my cervix, so I honestly ahve no clue, but I did have an abnormal pap about 2 years ago, went in and had a colposcopy and biopsy and had to go back for cryo treatment. In that short time I develped a couple of polyps which grew fast on my cervix. They were never tested though, they just removed them with all of the other abnormal cells. Could just be a growth like that. I wouldn't stress too much, just see your Dr. on Monday as quick as they can get you in, for your own piece of mind. Good luck.
