Two days ago I noticed that my breast was painful and sore when I touched it above the nipple. The same day I noticed that the same area was pink and hot to the touch. The heat and redness has calmed down but it is still tender and now I think I can feel a small lump but at times. I am not pregnant and not breastfeeding. I'm trying to get an appointment to get it checked out but no luck yet. Am I overreacting? There is a family history of breast cancers and breast cysts
