Red spots under my armpit

Ok I've had this problem before and I was on meds and now its back. I have tons of red itchy spots under my right arm pit, some even look like little zits. Last time this happened one of them got really infected and thats why I was put on meds and they cleared up. Now for some reason it's back I don't know if my period has set something off or if it could be a bad ravor. Has anyone has this problem before? I put come cream on it so the itching has stopped but im really confused as to what the heck it is and how to not get it again. If anyone knows how I can clear it up that would be awesome thanks.

My daughter has that!!! OMG! They are right in her armpit too. she's only 6 so it's nothing to do with your period. I took her to the doctor and she said to just leave them alone and they will go away eventually. It sounded kinda weird to me that the doc gave me that advice. I can't remember for the life of me what the bumps are called, it starts with an M. The doc also said they are in the wart family, not warts, but in the family. Its been about 4 or 5 months since we first detected them and they are almost gone. Just leave em alone. don't scratch or rub them.

it could be razor burn... I have had it 1 or 2 times but it goes away in like 3 days

It could be from shaving,thats happened to me a few times.
I know its gross,but stop shaving your armpits for a bit,maybe thatll help them clear up.

You ususally don't need medication for razor burn, do you? The razor burn I have had didn't itch, it burned and stung.

well I have that too, so it cant be from razor burn or your period because im a guy, I went to the doctor who told me it was a staph infection, and he said that even with treatment it can come back, so maybe you should just go to the doctor again because thats probably what it is.
