I'm in pains!!!!

Last Saturday, my sister had to call an ambulance. I couldn't breath properly. I was in serious pain from the whiplash. The pain was so much that I was crying in silence.
I was rushed to the A&E and was later prescribed Tylex which contains codeine. It knocked me out completely.
I went to work today but I'm still in pain even right now as I'm typing.
Meanwhile, a lot of paperwork keeps coming in the post from my insurer's solicitor and insurance company.
