What Causes Painfully Swollen Ankle?

WhaHi Three months ago I fell for reasons I do not know. The outer side of my left ankle swelled up with so much pressure I was unable to walk or even touch it. The first though from my GP was gout. The test levels indicated it was not. I was issued a steroid regiment (six the first day, five the next and so on) the next morning the swelling had gone down so much I was able to walk and the pain was gone. Six weeks ago coming down stairs my left ankle gave out. I fell down the stairs breaking my heel in three places. The pain and swollen is in the side of my foot again. I spent three days in the hospital when it happened. On the third day I had the worst pain attack on the side of the foot. I had enough of the doctors and nurses not listening to me that the pain was not from my heel it was from the same place as in March. I finally convinced the doctor what took care of the pain the last time and he prescribed me the same steroid regiment.The next morning the pain was now tolerable and I was able to be released from the hospital. It is two days short of six weeks now. I am unable to do any thing verticle for long periods of time. My ankle and pain is still on the outside of the foot and swollen. It resides all around that bone that protrudes out of the ankle. The ortho dr. doesnt seem concerned. I believe some of it comes from the insurance I have and me being indigent. Ido not thik that after six weeks that I should have the pain and swollen that I have. What are your thoughts? David
