Better safe than sorry! Sometimes tongues act up maybe you ate something that irritated it?, hopefully it's nothing... Did you call and tell them if there was a cancellation you'll take it? Try - it will help ease your mind if you get in earlier. The neck thing may be because you were sick. Keeping fingers and toes crossed its nothing! we've all been there and I - like you - question everything in my mouth if it's been there more than a week!
