5 months post op and still numb?

[Ripley119]

Hi all
As you guessed from the title, I am 5 months post op. The right nipple seems to have a very raised scar where the incision was made, but it's slowly getting beterb. My real concern is with the left side though. The top half of the nipple/areola is slightly puffy compared to the dead flat bottom half. There is also still some numbness surrounding the top half. My question is, is the numbness associated with residual swelling/scar tissue, or is just a coincidence? It doesn't feel hardhlike the scar tissue on the left side, but more softer. Im considering revision surgery if it doesn't improve in another few months.
It sounds silly but I can't really remember what it looked like immediately post op. I was worried about disrupting the healing so barely took a look the first few weeks.
Thanks everyone

Oh and FYI, it was gland only removal
