Around 3-4 weeks ago, I had gone sightseeing with a few friends, and I had worn a pair of shoes that fits snugly on my feet. After a whole day of walking, I felt uncomfortable and took off my shoes, which is when I saw that my left foot had swollen completely till my ankles, and my right foot was slightly swollen too. I sat with my feet raised for a while, and the swelling came down, but it remained for a few more days before coming down entirely. I didn't notice my feet anymore after that, since it had not hurt me since. But in the past few days I saw that my left foot was still swollen - not as much as the first time, but noticeable. Since then, I've been resting with my feet raised but the swelling has not completely gone down. There is a general ache in the leg as well. The area of swelling is only the top side of the foot. Footwear leaves depression marks on the foot.
