I recently rolled my ankle. Immediately following, it was difficult to bear weight, I felt light headed, and my vision started greying out for a few seconds. It then returned and I felt fairly normal and my ankle was slightly sore (but not painful or intolerable). Later that night, it was very sore and hurt to walk. However, the next day it was slightly sore and I did not feel pain while walking. But it was swollen the second day. Should I seek any medical attention since it doesn t currently actively hurt?
