Is there anything I can do to increase nerve regeneration? (Photos)

I had surgery almost 5 months ago and I still have very little sensation in my nipples and areas of my breasts. The left nipple had some feeling in after about 6-8 weeks but that seems to have tailed off a bit now. I am desperate to get some feeling back. I feel like I have broken my body with this procedure. Is there anything that I can do? Is there a procedure available that would restore feeling? I need to get my feeling back as it is affecting my sex life adversely. Please help
