She gave her birthdate as July 7,1910, but her birth certificate shows July 6,1907. At age 6, Frida was stricken with polio, which caused her right leg to appear much thinner than the other. It was to remain that way permanently
On September 17, 1925, at about age 18, Frida Kahlo was involved in a serious bus accident which left her with a broken spinal column, a broken collarbone, broken ribs, a broken pelvis, and 11 fractures in her right leg. In addition her right foot was dislocated and crushed, and her shoulder was out of joint. For a month, Frida was forced to stay flat on her back, encased in a plaster cast and enclosed in a boxlike structure. Frida's enormous strength and will to live allowed her to survive and make a remarkable recovery. She began painting shortly after the accident because she was bored in bed. This became her lifelong profession. Frida let out all of her emotions on a canvas. She painted her anger and hurt over her stormy marriage, the painful miscarriages, and the physical suffering she underwent because of the accident.
