According to WebMD, some at-home shingles treatments include avoiding picking at blisters, using cool and damp compresses, soaking crusted sores with tap water and applying baking soda or cornstarch to help dry sores. Nonprescription pain medications are also used to treat shingles at home.
WebMD advises consulting a doctor about using over-the-counter pain medication if the patient is already taking prescribed pain medicine. Some prescription pain medicines contain acetaminophen, and too much may be harmful. Controlling pain from shingles immediately may help prevent nerve damage, which can cause pain that lasts for years. Shingles, a viral infection of nerve roots, affects about 1 million people in the United States each year.
