Hi Jancis, 18 mo ago I had a car crash also. Mine however was a headon and I had a hard shock on the right side.(was hard on the brakes at impact)
My preexisting condition was diabetes. Didn't show any symptoms for four days. First symptom was a burning pathway from the hip to the inner knee. In hindsight I would have kept a log or journal of dates, tests, symptoms, etc. I will not go into more detail about my journey. I have learned that nerve regeneration is a slow and tedious process. I guess that lawsuit and lawyers and perhaps some specialists may get involved. Please don't let anyone rush you to any finality. I hope that Mrs.D's advise will be sufficient to get you back to normal. Anyway, write down how you were before the accident, because normal will be scrutinized. Good Luck, Ken in Texas, USA.
