HN,
Probably pain from tension...you are an upper body tenser, right? Me too! ;p
...made worse by the dental stuff (tensed up in the chair)...further aggrivated by the wallpaper removal. (reaching up and using muscles that aren't typically used.)
I am sure it is nothing to worry about, but as Hibee said, keep an eye on it and get checked if it doesn't improve, or it gets worse.
For now, rest it and do some gentle stretching.
