I've never had sensation in my nipples. Is that just the numbness of my nipples? (Photo)

Most breast reductions lead to some nipple and sensitivity this is common as the tissue that is removed around the breast often carries nerves to the nipple unless you had a free nipple graft you will regain some of the sensation

It is common to lose or have altered sensation in the early days after a breast reduction.  Both breasts may even feel different.Over time some, or all of the sensation will return & this can often be preceded by weird feelings & electric shocks or increased sensitivity.You shouldné be worried about what you are experiencing.All the best - you seem to have a nice result.

Your nipple sensitivity may change after surgery and often this is temporary related to swelling.  Once the swelling starts to subside the sensation usually improves.
