How Can Pain And Discomfort In The Ankles Be Treated?

I have blood pulling in my ankle/foot after injuring my upper leg (knee). This is causing discomfort while walking. Is there anything I can do to make this go away faster? SERIOUSLY !!! YOU WANT ME TO PAY FOR A SIMPLE ANSWER TO A SIMPLE QUESTION. NO WONDER WHY THE HEALTH CARE SYSTEM IS IN SHAMBLES. I WAS TRAINED AS A MASON IN THE AIR FORCE ,BUT I CAN NEVER REMEMBER CHARGING ANYONE FOR A SIMPLE QUESTION THEY MAY HAVE ASKED ABOUT DOING CONCRETE OR LAYING BLOCK. WHAT A FUCKING RIP OFF !!!
