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.
Heredity and Age: Individuals with family history of swollen under eyes are more prone to it and are likely to develop it at some point in life. Aging is another contributing factor towards the occurrence of puffy under eyes. Injury: Injury close to eyes or around the eyelids can also cause the eyes to swell.
