Skin on scalp is tender, sensitive and bit painful if touched. hurts once in a while, in same spot. didn't hit myself but feels like it, like a bruise?

See an osteopath: It may be difficult to determine why this is happening unless it is physically examined by an osteopathic physician. They may find that there are certain structures on the skull that may be more tender than others that may be on a suture line, or edge of a bony prominence on the skull. You receive more information, once this examination is done.
