I have been pumping for work the past couple weeks. I initially had the pump on a relatively high setting, but my nipplrs seemed sore and almost butning for hours after, so I have hadit on a much lower setting since monday. I have also taken a day break on the days I don't work. I pumped yesterday morninng and it was quite painful, even on a low setting. When I was done my nippples were prple and bruised. I pump for 15 minutes at a time with a medella double pump. What should I do? My little guy needs milk while I am gone but I am in a lot of pain. Luckily BFing isn't (very) painful.
