I was in a car accident yesterday. My car skidded on ice and hit a skip. I went to hospital and they said I was suffering from shock (had headache and nausea all day) and muscular pain (pain in back and shoulder). Today I've had pains in my abdomen (both sides) all day, along with pain in my lower back (I have had arthritis although no pain recently), pain in the backs of the thighs, hips, down side of leg and knees. Could this be a hernia.
