Head pain on back right side

I started having pain in the back of my head on the right side on my head just behind the top portion of the right ear.  It is a constant pain and sometimes intensifies but goes away quickly.  It is starting to go towards the back of my right eye but is still painful in the back of my head, even when you touch it.  I have tried all the OTC medicines but nothing is working.  Can you help me find out what this is or what I should do?

Thanks,

Pam
