Pain is now going up my leg?


I’m almost 62 I was in my garage working on a car a tool fell on floor I got down pick it up i started back up almost standing straight up and lost my balance fell on hy knee maybe a tool. This was last Saturday, never hurt knee, but, hurt left side of leg below knee, thought maybe broke leg, I have no insurance I work for a week pain left that area, but is now going up my leg almost to top. should I be worried of a blood clot This morning my leg was red some It seems to be okay now, even pain not bad. Was headed for hospital. Should I wait Thank You
