I keep getting cancor sores on my tongue and at night, my mouth is so dry that my tongue sometimes sticks to the inside of my mouth. It happens during the day also. It is not too dry in my house and I don't think I'm taking any medication that would cause this. I do have issues with the back of my neck being stiff. I'm going to ask my doctor if I could get an MRI. I have already gotten xrays that showed some arthritis, bone spurs and there is no cartilage between the vertibre. I feel like I'm a hot mess!
