The outbreak following the initial infection (usually a few days to a few weeks afterward) is usually the worst -- the ones after that are less painful. The infection lies in a cluster of nerve cells near the ear called the trigeminal ganglion. HSV-2 generally results from genital contact with blisters in the genitals, anus and inner thighs, and it lives in nerve cells in the sacral ganglion, near the base of the spine. Urinating can be extremely painful when having an outbreak of HSV-2 as the urine hits the open sores. Early after infection, some people experience prodrome, a tingling, itching feeling that occurs in an area where blisters will shortly develop. HSV-1 infections can also spread to the eyes (herpes keratitis), face and chest (herpes gladiatorum), and fingers and thumbs (herpetic Whitlow).
In rare cases, it can spread to the brain and cause herpes encephalitis or Molliet's meningitis, types of brain inflammation that can result in death.
There has been some research associating herpes simplex viruses with Alzheimer's and Bell's palsy, although definitive links haven't yet been proved.
