My TMJ is also the result of a car accident. That happened in April 2001 and I am still waiting for the other guy's insurance to settle. I have an attorney and will probbaly end up in court.
Five months after the accident I was pregnant with my 5th baby. The extra weight (I gained 30lbs.) made my whiplash symptoms worse, which in turn made my jaw worse. One of the biggest(LOL) problems was my breasts. I go up several cup sizes during pregnancy and breastfeeding. After the baby was born, carrying her and breastfeeding caused pain. I would have to be extra vigliant about my posture and not hunch over her. After trying PT with no results, my doctor gave me the okay to see a chiropractor with no adjustment of my lower back. That was the only relief from the pain.
