Back/Neck Friendly Exercises

So, last Wednesday, I was in a car accident. I was REALLY lucky with only a few minor injuries (mostly bruises all up on my legs and some minor whiplash) and, really, all I want is to get back into the gym to work off some stress.

However, I went in on Monday and did my normal weight routine (some weighted squats/lunges, kettlebell swings, arm stuff on the ropes, tricep dips... nothing too extravagant) and by Monday night my neck and upper shoulders were so sore I could barely sleep. So, obviously I’m aggravating something there and need to do some re-vamping for the next little while.

I was hoping there were some other people here with delicate necks and backs who might be able to make some suggestions to tide me over until I get all healed up.
