What causes occipital neuralgia? Occipital Neuralgia may occur spontaneously, or as the result of a pinched nerve root in the neck (from arthritis, for example), or as the result of prior injury or surgery to the scalp or skull. Sometimes âtightâ muscles at the back of the head can entrap the nerves.
Puffy, swollen eyelids and dark circles under the eyes can occur when you have an eye infection such as pink eye. These swollen eyes are caused by inflammation associated with the eye infection, which directly affects the neighboring eyelids. Also, dry eyes can cause general puffiness and swelling.
Eyes tend to get puffy due to water retention, which is caused by a high concentration of salt in the area around the eyes. If you ate a very salty dinner or cried before bed you might notice increased puffiness in the morning. Drinking plenty of water flushes the area and causes the swelling to go down.
