Sore, swollen knuckles?

Em

My hands are very mildly swollen (I’m 31 weeks) but my knuckles are sore and much more swollen than the rest of my hands. I can hardly twist the cap off of a water bottle. I feel like I’ve developed arthritis! 👵🏼

Is this normal for pregnancy and just related to the excess water? Can I expect my knuckles to return to normal after I give birth?
