<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello Doctor. I have a question regarding occasional skull pain with sharp shooting pains that make me stop doing what I am doing, then it goes away as fast as it comes up. today I have had five while in the grocery store and continue to have them now that I am home.  <response>: There are different kinds of stabbing headaches, but the first I can think of corresponding to your description is cluster headache HA, which is a primary HA which is rare, and happens more often in adult male smokers. Cluster HA is commonly one-sided. The HA happens in clusters every day for a number of days or even weeks. It disappears for months then, but can happen again. To abort a HA you can use oxygen 100 by mask, or trip tans like sumatriptan subcutaneous or ketamines intravenous. The prophylactic treatment consists of calciblockers verapamil more often and corticosteroids.
