For exclusive pumping women

Ka

So my little turned 2 months today. I’m exclusively pumping with maybe him latching once every 2 weeks only. He hasn’t latched on my left side since leaving the hospital. After I get done pumping ( I pump till I don’t get any more drops) my nipples throb. This has happened for about 2 weeks now. I have a spectra 2. Any ideas to ease the pain?
