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 lacrimal gland, which secretes tears, lies over the upper, outer corner of the eye; its excretory ducts branch downward toward the eyeball. A constant stream of tears washes down over the front of the eye and is drained off through two small openings located in the inner corner of the eye. Through these openings the tears pass into the lacrimal canaliculus, then through the lacrimal sac into the nasolacrimal duct and finally into the nasal cavity.
