Back of my head is hurting bad and feels slightly swollen(Size of a 5p). After this came up a few days ago now I have this all over itch which is just unbearable and now a small raised rash on my breat bone. I had this type of pain last year when I got shingles. But no itching. I have no other symptoms. Maybe some general aches and pains. But nothing major. Could it be re occurring shingles ? I'm a bit worried now since I couldn't help myself and decided to google and lymphoma came up too with my symptoms
