Unfortunately I don’t have any advice for you, but my husband is the same boat as you. Friday marked his half way point and he’s in so much constant pain. He uses magic mouthwash, that temporarily takes the pain away. He’s on a liquid only diet and it needs to be very bland, or it irritates his mouth. He also take 5mg oxy, which isn’t helping much. His spirits are pretty low and he’s not sure how he’s going to get through the second half of this treatment. He has an appointment with his doctor tomorrow, so I’m hoping he can get something to help with the pain.
