You can get shingles on your arm. According to WebMD, a shingles rash can show up anywhere on the body; however, the rash will only appear on one side of the body (the left or the right).
WebMD indicates that early-warning symptoms of shingles include headache, light sensitivity and flu symptoms without a fever. In addition, the affected area sometimes itches, tingles or experiences pain.
The Mayo Clinic states that shingles is caused by the same virus that brings on chicken pox. In some people who have had chicken pox, the virus rests in the nervous system and shows up years later.
