Has anyone had one? My GP said I may have one but will need to go for more tests next month. I've had bad headaches, both migraine and 'normal' ones and they are always in the same place in my head. I have dizzyness and pins and needles in my hands and sometimes numbness. I also have visual disturbances. These are not migraine auras as I get an aura an hour or 2 before the migraine comes on but I get these symptons most of the day every day.I m currently on Nordolol (beta blocker) to stop the migraines and they are working but I still get the general headaches. My periods have now stopped. My blood tests show I am not producing much prolactin which is made by the pituatary gland. Does this mean I have a tumor. Please help.
