Suggest Treatment For A Swollen Knee After A Fall

It is pretty much just like the question below. I hurt my leg when I fell from getting caught up in my cats toy. I went to the emergency because the area below my knee swelled really fast and it looked as if I had another knee. It isn t my knee that hurts, but under my knee where it is still very swollen and it was bleeding up until yesterday (just a little). Now my ankle is black and blue and swollen. I am afraid of getting a blood clot, but my ankle does not hurt, but under my knee is still swollen, and hurts. I don t want to go to the emergency room again, but I am really afraid that something is wrong. I took my mom to her heart doctor yesterday and he just looked at my knee. He gave me Ciproflaxcin HCL and I wasn t swollen in my ankle yesterday so I didn t get the prescription filled. I am getting two implants done soon and I know I am going to have to take pills then so I am hesitant to take anything. I filled the prescription a few hours ago, because of the ankle situation. Do you think I should do anything else. I am going to ice it again in a few minutes.
