Phantom Beard Syndrome
Similar to phantom limb syndrome, Phantom Beard Syndrome (PBS) occurs when a man has had facial hair for an extended period of time and then for whatever reason decides to shave it. He is likely to still think the facial hair is there, feel it, or even attempt to stroke it even though it is gone.
I shaved off my goatee before joining the army 4 years ago and I can still feel it today. I thing I have Phantom Beard Syndrome.
