Swollen occipital bone and nodes near it very itchy, also itchy rash all over my body. What can I do.

In the meantime try antihistamine like benadryl (causes drowsiness) or Claritin (loratadine) which doesn't cause drowsiness. Try to think of any new exposure to foods or other substances. ...Read more

If not very sick, probably a routine virus. ...Read more
