Healing Challenges After Breast Lumpectomy: Nipple Pain and Changes

I am 4 weeks post lumpectomy. Had previous lumpectomy on left breast 12 years ago and only issue I had healing was an allergic reaction to surgical staples. Right breast , current bc, the cancer was located deep below the nipple. Have a 5” incision at 9 o’clock and basically between 6 o’clock and 10. The incision goes into the edge of the nipple. As I heal there are three issues that I have questions for. Did you experience extended hard nipples that went on for hours and was painful? Did you start to get inverted nipples? Did you stretch a bit too high and cause a horrific pain in your breast and restart the painful nipple situation?
