I am 13 years old and I have some lumps in right armpit they're inside the skin I only feel them when I put lots of pressure and they're painless and little smaller than a pea and are soft and a little hard and moveable can this be hormonal I also have some breast lumps and got them checked and the doctor said it's nothing to worry about your breasts are developing, I started my periods 4 months ago is this okay ,I am very scared.
