Minimal feeling in nipple after breast reduction?

I got a breast reduction on June 11 (about 8 weeks ago) and am so happy I did it! However, something that I have noticed is that my right nipple has normal feeling while my left nipple has very minimal feeling. At first, I usually cannot feel anything. Then, after repeated stimulation, sometimes I can feel a slightly dull painful sensation. The areola also appears more puffy than before. I had an anchor reduction and about 250 g removed from both sides if this helps. Thanks!
