I woke up last saturday morning with 2 red bumps on my arm . They were somewhat swollen and sensitive. They also had white heads. I thought maybe it was just acne , so I popped them. The bumps have not gone away and are spreading. Each one has a white head on it. The morning I woke up with them, the bumps were somewhat sensitive to touch, but now they aren t sensitive at all, and are rarely itchy.
