Since you're having pain in your jaw when you open it it might be a good idea to call the surgeon. It's possible that you have inflamation in your jaw. I kind of experienced the same thing after my wisdom teeth were extracted and I just took a round of Anaprox to reduce the inflamation. If you still don't think you're ready to go back to your normal diet again just eat softer foods and gradually work your way back into other stuff. Grilled or baked chicken, salads, potatoes, potroast, ground beef, and so forth shouldn't be too bad. The main thing is just to make sure that you're not packing food in the socket, that can make things very painful for you. If possible get a syringe and irrigate the sockets out gently after you eat and you shouldn't have any problems. Everybody heals differently, so don't get discourages. Call your surgeon and discuss your concerns with them. The least they'll do is give you some peace of mind. I hope everything gets better.
