I have a cold sensation in my forehead. numb/swollen feeling behind left eye. dealing with correcting pinched nerve in neck with chiropractor for about a month. ?

Sensations: The sensations of the forehead and the left eye,if on the same side, may well be interrelated and could be due to a slight irritability or inflammation of the supraorbital nerve-a type of neuralgia. I don't believe that the pinched nerve in the neck is related unless treatments stirred up the forehead neuralgia. If symptoms persist or worsen, consult both a neurologist and an ophthalmologist.
