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.
1 Sleep deprivation - Interrupted sleep cycles are common causes of eye puffiness.  Fluid retention - Many conditions (including pregnancy and hormonal variations with menstruation) can lead to the retention of fluid, particularly in the subcutaneous tissues. These conditions can cause swelling around the eyes to be more prominent.
