11 days post full upper arch implants. Now the pain on the roof of my mouth is beyond tolerable is this normal? (photos)

Although some swelling , pain and sloughing is normal after 10 days but this swelling is approaching a lot towards the palate. It's better you visit the doctor in person for a review. You can do warm saline rinses(Add a tablespoon salt to a glass of lukewarm water) 4-5 times in a day for a quicker healing....Hope that helps ....wish you a smoother less painful healing 

You should go in to see the surgeon in person. It could be necrosis of the tissue or bone. It could be a reaction to the anesthetic or materials used. It could be a viral infection. It's difficult to tell from the pictures provided.
