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.
As you age, the tissue structures and muscles supporting your eyelids weaken. The skin may start to sag, and fat that is normally confined to the area around the eye (orbit) can move into the area below your eyes. Also, the space below your eyes can accumulate fluid, making the under-eye area appear puffy or swollen. Several factors can lead to this, including: 1  Fluid retention due to changes in weather (for example, hot, humid days), hormone levels or eating salty foods. 2  Not getting enough sleep. 3  Allergies or dermatitis, especially if puffiness is accompanied by redness and itching. 4  Heredity â under-eye bags can run in families. 5  Symptoms.
