tongue/roof of mouth feel cold. for the past week part of my tongue and part of the roof of my mouth have constantly felt cold, at times like a cold burning sensation and it really bothers me :( there's no pain or change in color in the area and it's not my entire tongue or roof of my mouth, it's just sort of in the middle.
Listen. The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. When the retina detaches, it is lifted or pulled from its normal position. If not promptly treated, retinal detachment can cause permanent vision loss.
The nasolacrimal duct is the structure ensuring tear drainage from the surface of the eye to the nose. Tears are produced by lacrimal glands located around the eye. A continuous supply of tears is needed to provide nutrition and to wash away bacteria from the surface of the eye, two small openings or Ã¢â¬Å¾punctaÃ¢â¬Å are present in the inner corners of the eyelids which allow tears to enter the nasolacrimal duct.
