engorgement help

I had to express on my left side due to engorgement so baby girl could latch. 30 minutes after she ate she was rooting again and to avoid the same pain on my right side I made sure to have her eat on that side. Another 30 minutes later she was rooting again so I gave her my left side again. I'm worried this will cause me to get engorged again. What can I do to help with the pain and keep from getting engorged?
