Raw grapeleaf juice caused severe swollen ankles?

I drank a bunch of raw grapeleaf juice for the first time two weeks ago and I think my body reacted badly because now I have really swollen ankles with pitting edema.

It has been swollen for two weeks now. Also my leg joints are kind of sore but I think that's from the swelling. I don't feel any other negative symptoms (no headaches nausea tiredness).

I am afraid I damaged my kidneys.

Anyone have any ideas for me? Thanks.
