My ankle started hurting around a week ago. It hurt to walk and its pretty painful. I thought I just sprained it or pulled a muscle and that it would go away over time.

The ankle pain is not going away and now the pain is in my shin and knee on the same leg. The pain is achey and sharp. I think my knee is a little swollen and it hurts more if you press down on it.

On my knee, there are also some red marks. I thought those would go away in an hour or so but they're still there. The pain is only getting worse and I don't know if these things can even be connected. Some advice would be greatly appreciated. Thank you!
