Should I consult with an attorney with all the stress and total loss from a car collision?

We were the 2nd car out of 4 when the 4the car plowed into the car behind us, which hit us hard, making us hit the car in front of us. We were all stopped. Our car was towed away. In my vehicle were my wife and 6 year old child. We were in south of New Jersey commuting from Pennsylvania in the way to the shore. We stayed a few hours after getting dropped off at enterprise from the police to get a rental to calm down. My wife and I had neck pain and headache. We went to an emergency room when we got home. I had a CT scan and my report assessed me with a concussion. My wife was assessed with whiplash. My wife is in-between jobs, and was in interview process, just wondering if I should get a consultation. I also took many pictures. Our insurance also only covers 1000 for the rental. We might not have another car.
