Has anyone been given a cortisone injection while breastfeeding? I have tendinitis in my wrist and my orthopedic surgeon said he wouldn't do the injection because it is very controversial. He did say if I got a note from my OB OKing it then he would absolutely do it. I did a quick google search and found lots of women who had it done no problem. Some said they just didnt bf for 4-8 hours after the injection.
