The headache is usually dull, aching, and throbbing. Bending or stooping may worsen the headache. Fluid retention within the sinuses around the eyes can cause similar symptoms, but less severe. Sometimes sinus congestion or infection can be associated with obstruction of the tear drainage system . This leads to frequent tearing of the affected side, and possible infection of the tear duct.
Shingles refers to a reactivation of the chicken pox virus along the distribution of a nerve.
Once a person has had chicken pox, the virus lies dormant in nerve cells. The nerve that supplies sensation to the scalp, upper eyelid, eye, and nose is commonly involved, and the rash may appear in this area. Note that the rash never crosses the midline of the forehead, and this gives a very obvious appearance. The area involved is usually painful, with a burning aching. This pain may precede the rash.
