How long does it take for teeth sensitivity and gum pain from porcelain veneers to go away? (photos)

I had my veneers placed about 6 weeks ago. When I had the temporaries on I started experiencing sharp mouth pain. The dentist said the pain should go away after the the veneers were placed but I am still in pain. I went to another dentist after the veneers were placed but my X-ray came back normal. I am on painkillers everyday because my teeth are sensitive, my gum aches and at times my jaw hurt. Will the pain ever go away? I had 16 veneers placed (8 at the top and 8 at the bottom).
