Potential long term dangers of Ambien. Using sleep hypnotics such as Ambien for more than 4 weeks can lead to damaged sleep staging and addiction. If taken for longer than 7 to 14 days, Ambien can provoke insomnia that is actually worse than the insomnia the drug was intended to treat.
Two Types of Pinched Nerves. A pinched nerve can cause symptoms either locally, exactly where the site of entrapment of the nerve is, or it can cause symptoms that are distal, which radiate from that pinched nerve site down the arm, or down the leg or to other parts of the body.isual Demonstration of a Pinched Nerve. I'm going to show this on a smaller model set of the spine. Here I have two of the lower spine vertebrae: the L4 and the L5, or 4th and 5th lumbar vertebrae. These vertebrae are held together by elastic so it's very easy for me to demonstrate what a pinched nerve looks like.
Glaucoma is diagnosed using three pieces of information: the appearance of the optic nerve, the eye pressure, and the results of specialized testing. Optic nerve-the optic nerve is like a telephone cable that connects the eye and the brain. It has the appearance of a yellow-orange circle in the back of the eye.The circle actually looks more like a crater or donut in three dimensions.Glaucoma causes changes in the appearance of the optic nerve â the crater gets deeper with thinner walls, or the donut gets a much bigger hole and a thinner rim (see diagram to left).he circle actually looks more like a crater or donut in three dimensions.
