My daughter is 8, she has very pinpoint tiny bumps starting from under her left arm, going down through her armpit down onto the side of her trunk. The bumps are very small, look clear, and seem to be filled with something, but when we try to "pop" them, they don't pop, nothing comes out. She says they itch. We have a doc appt tomorrow, just wanted to find out if you knew what they were, I've looked all over the internet and can't get an answer.
