Sharp, throbbing pain behind ear (NOT IN EAR)

Hello!! Anyone ever have a stabbing, throbbing pain BEHIND right ear. . . I can actually feel the throbbing. . . I have this pain along with facial and right eye pain. . . I feel like yanking everything out and. . . . . . .I lay in bed for 3-5 days in a week feeling this way!! All responses welcome! Thank you! I have been told I have Chiari, but, was decompressed last November, and it did help with some of the pain which felt like being hit in the head with a 2x4. . . .
