For the past week and a half or so, I have been getting dull, sort of throbbing headaches behind my ears (picture attached); mainly on the right side and mainly only on one side at a time. It makes my right eye hurt a little too. I take tylenol for them and they go away for a bit, but then they come right back. Also, I have been having a similar dull pain at the base of my skull, but that is less often.
I have been under a bit of stress lately, but I don't remember getting this under stress before. I wanted to know if it's anything I should be worried about.
