What Can Cause Pain On Back Of Head,ear And Jaw And Sensitiveness In Scalp?

Hi. I have been experiencing pain on the back right side of my head and ear/jaw. My hair scalp is sensitive too. I've taken Ibuprofen and it goes away but comes back. It's been like this for 2 days now. Can you help me get rid of this? It's not tension on the scalp or an ear infection is it? Thank you.
