For the past 3-4 days a sharp pain at the left side of head, about even with the front of left ear but on the top of head. Lasts for 5 to 10 seconds then goes away. Happening very frequently throughout the day. Sometimes happens as often as every 5 to 10 minutes apart. Not dabilitating, but worrisome and annoying. I don’t get headaches except slight occasional sinus headache. Had top right wisdom tooth pulled last week Monday, with no issues, but seeped blood until Friday.
