This Leg

What am I going to do about my left leg (and foot)? I keep injuring it over and over with my silly tripping. Not sure what I can do about it . I was in serious pain today and the stiffness is worse. The Advil didn't work at all. I decided to try some aspirin which has helped a bit.
Should I call the doctor ?
Now the entire knob on the new washer has fallen off. I have to call a service person in the morning because naturally when it happened they were already closed. Nobody in this town works past 4:30 during the week it seems. Can't get use to that.

I really need a sleeping pill tonight.
