This past Saturday, I was walking up a sidewalk to enter a store. For some reason, my legs or ankles suddenly gave out and I fell down(I have a history of falling down). I fell forward on my hands and knees and it felt like I had the breath knocked out of me. I got up, shook it off and just tried to stay off of it for a few days. Sunday, I noticed that from the top of my knee to the base of my toes that my leg was numb. I blew it off thinking perhaps my natural endorphins had kicked in to prevent all the pain. The numbness initially was just down the top of my leg, but now it's numb the entire top half of my leg and I can still feel excrutiating pain on the sides of it. In addition, the entire leg beginning about 3 inches above my knee all the way down is swollen twice as big as my left leg. I'm self employed, have no insurance and a very small bank account. I know I need to see a dr, but I don't want to waste too much money since I really don't have it to spend. Can anyone here give me some advice on what I can do?
