Joint pain in fingers


I’m 3 weeks pp from my 3rd pregnancy, and up until this go-around I have never experienced it before. It started in my 3rd trimester, but I’m having stiffness in my fingers.. especially in the morning. It’s not unbearable, but it is uncomfortable/a bit painful. Has anyone else experienced this? I’m also EBF, if that matters at all.

Thank you in advance!
