For the last month I have been getting a random light throb in the left side of my head. It doesn't really hurt but comes and goes day-to-day. Sometimes the throb occurs every few seconds and sometimes every couple of minutes. I have had hemiplegic migraines for about ten years. This throb is in the same spot that I get a ice-pick headache when I get a full-blown migraine attack. It seems to get worse if I eat a lot of sugar. Anybody else have something like this??
