Post Partum finger Swelling?

Zuheily

Ladies I am 5 days PP and my ring finger on my left hand is so swollen I can hardly bend it or even make a fist. This started happening maybe like 2 weeks before I gave birth. When I gave birth it got slightly better for 2 days but now it seems worst. Has this happened to anyone else? Idk what to do but I can hardly use that hand for anything.
