I twisted my ankle 2 days ago and the next day it started to swell but today both of my ankles are swollen. Why is that?
See your primary MD
It is doubtful that the twisting injury produced swelling in both ankles, I would advise you to seek evaluation by a medical professional.
Since you are having abdominal symptoms and bleeding, the swelling in your feet may be signs of edema from a more serious condition.
