A Background Of This Leg.... Torn Meniscus(3 Yr. Ago), Feb.

A background of this leg.... torn meniscus(3 yr. ago), feb. 2016, broke my ankle, metal plate, screws, and now I have been having some numbness in the left foot, specifically my toes. Some pretty severe knee pain, groin pain, as if I had pulled a muscle. (?) Am I crazy for being concerned? The groin pain and numb toes have recently, gradually started (3 weeks...). Painful when I drive, so I try not to . I'm 57, 5 ft 2, 190 lbs. which doesn't help.....and I am active, farm life.
