Car Accident Injury: Need Advice on Taking Time Off Work

I'd highly suggest going to a chiropractor or physical therapist, they've worked wonders for my friend

Your body went through trauma, it needs proper time to heal! Try resting and maybe doing small things at home to feel productive. Read a book, eat a good meal, finish a show you've been wanting to, etc. You will benefit a LOT from letting yourself heal, if you try to "push through" it may never fully heal and could cause problems in the future. Stay strong, but do take it easy <3
