I have had a headache for about a month and a half, every day, intermittantly through out the day. I have not changed habits, blood pressure is fine, no specific time of the day that it occurs. occurs behind and in the right eye only, and right side of the head. imitrex did not help with this, pcp is not contacting me back. pain is approimately a 8/10 at worst, 5/10 when it is just moderate to mild. please help
