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.
Fluid retention, salt (sodium) intake and lymphatic drainage. When the skin cannot get rid of excess fluid in the tissues it will result in edema (oedema). This will cause puffiness and can also contribute to dark rings and circles under the eyes. There are various factors that cause fluid retention.
