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 Allergies - Allergic reactions can lead to leaks in the subcutaneous capillary beds which can cause swelling in the face, including around the eyes.  Skin disorders - Eye puffiness can be a side effect of certain skin disorders, such as dermatitis, if the affected area becomes very sensitive, leading to swelling.
