A few weeks ago I visited my GP because I have been having pain in my right breast. I was examined and the GP said that she couldn't find anything to worry about. Yesterday I started prodding about and I can feel a tiny lump that moves in my breast near my armpit. I can only find it if I use the tip ofof my index finger and if I use the pads of my 3 fingers I can't feel at all. Do you think I need to go back to my GP or if I can't feel it when examining with 3 fingers should I not worry. Could it be a gland? I have my period at the moment.
