Is there a correlation between being sick and getting a head rush more easily?

For the last week and a half I’ve been getting a throbbing head rush very easily. I’ve been fighting a cold for about the same length of time, but it finally beat me and I have a throat and chest thing. If I cough, bend down, reach up, sneeze, hold my breath for hiccups, turn my head too fast, yell up the stairs, etc. I get a nasty painful head rush. Also, there is there another name for head rush? I’m not sure that’s the official name for it and that most people won’t know what I’m talking about.

Anyway, does having a cold have an exaggerated effect on head rushes? If not, is there a common problem that causes them?
