It could be. But to be on the safe side you should call your Doc and ask him to refer you to a Neurologist and get an eeg done. An EEG is a video recording of your brain waves. It is painless, and you will most likely get some answers. Also you should probably get an mri and a catscan.
Hi,
How are you? Short, stabbing, extremely intense headaches that can last for a few seconds may be caused by ice pick headaches. This may occur in patients with primary headaches such as migraine or cluster headaches, and may not be due to organic causes. However, if it persists, it is best that you have this checked by your doctor for proper evaluation. Take care and do keep us posted.
