Recurring Head Pains

Hello! I have stumbled across your web site and hope it may give me some answers. I have had recurring head pains for 10+ years (I am a 38 year old female). Several years ago I was hospitalized, given a nerve block shot in the head and told I had trigeminal neuralgia. After reading your information on this, the type of pain description is similar but the location is not. My pains are almost alway toward the back of the skull, upper and lower regions, never near the face. The onset is sudden and severe and can stop me in my tracks. I have thought for a while that they must be nerve or artery related. I notice that if I bend my head over or tilt it the pain can worsen. If I step down a stair funny the pain can come rushing. No over the counter medications have helped. I go for periods of time without any pain. I am now on day 4 of severe pains in the evening and the only thing that remotely helps is putting pressure on the site along with ice sometimes. I have also been told this has to do with my occipital nerve. I have had a few odd viruses as a child and am not sure if this has any relations. I have also noticed in the last 10 years or so that I have increased tingling in my hands and feet, feelings of weakness, and some memory issues. I discovered with my pregnancies that I was slightly anemic. Any insight would be most helpful as I am at the end of my rope with testing and traditional MD's. Thank you so much for your time and consideration!
