[|Human|] I had shingles one year ago on my head, and it involved my eye.  Today I have developed an irritation/itchy spot on the eyebrow of the same eye.  How will I know if shingles is returning?  A second, but separate question is: if shingles recurs in my eye what will the symptoms be like?   And what would the treatment be?
[|AI|]  Hi, Welcome to Chat Doctor. Shingles is herpes zoster infection which has the tendency to recur. This recurrence is because herpes viruses have the property of remaining dormant in the body in the nerve cells and getting reactivated when the resistance of the person falls. However, these reactivated lesions present similar to primary infection but are usually less severe and less painful. I suggest you get the itchy spot examined by your testing doctor to confirm reactivation of herpes zoster. Treatment of this condition will remain same. Most effective is acyclovir. I hope I have cleared your doubts. Thanks.
