swollen fingers

I typically have swollen fingers when I run/exercise, but lately I’ve woken up with such swollen fingers that I can’t get my engagement ring off without a fight. I have not increased my salt intake and I don’t know what to do about it. I’ve been attempting 64 oz. every single day, which is more than I used to drink - so I understand that my body might not be used to as much water. However, it has been over 3 weeks of this. One would think it would start to go down.

Keep swimming.
