I am 7 days after breast reduction /lift. I have numbness and heaviness under my arms/sidebreast around my ribcage?

7 days ago I had breast reduction /lift. It was the W pattern. I was on larger size, so my Dr had to cut a little futher back on my sides and do a little lippo around side ribcage underarm. When I get up from lying(elevated of coarse) I feel the numbness and heaviness shifting it feels. Dr done good job, nipples got feeling back quick, still a bit hardness and swelling, its the sides that are really my pain. How long will it take to get that feeling of dropping shift numbness to stop?
