Fish Oil compared to flaxseed? esp. for healing purposes....Advice

I have whiplash and my chiro told me to take a multi with everything. She knows I follow a mostly vegan diet and was cool but I got the strong impression that the multi with fish oil would be better absorbed and help me feel better than the one without (she said that one had everything). I wont take it if I am not comfortable but was wondering if you had opnions.

I want my body to heal- my ligaments are loose from the accident. I know one thing is not a cure all but still opnions appreciated.
