Large Scab Covering Nipple Still After 3 Weeks of Breast Reduction, How Can I Help It Fall Faster?

I had an extensive breast reconstruction and implant surgery 3 weeks ago, after the first week of surgery my nipples scabbed and doctor explained it was because of poor circulation due to the length of the pedicle, I'm still in treatment and the right nipple is on track, but my left nipple is running behind, i would say 50% of nipple/areola is covered in scab, hurts and bleeds which doc says are good signs, but is there anything i can do tohelp expedite the process??
