What to use on nipples? 7 year post surgery breast reduction

I had a breast reduction 7-8 years ago. I have Hypo- sensation. When my nipple itches, I feel it in other parts of the breast. I had nipple graft reconstruction. I have tried Vitamin E oil, straight Lanolin, diaper cream, shea butter, coconut oil and vaseline curb the dry itching cracking and minuscule bleeding of my aerola. Recently, had a barely visible amount of blood on the "pasty". Worn to prevent chafing. My doctor acted like it was normail for this to be happening to me. I need help.
