Headache when touching the eyebrow
Hello,
When I touch my left eyebrow, stroke it, or touch it with a towel, I feel a stabbing pain in my head, starting near the eyebrow and radiating to the left side. Sometimes, there is also a slight pain in the region without any touch, which could also be partially due to the wind.
I had these symptoms for a longer period (8 weeks) half a year ago, and now they have reoccurred.
What could be the cause of this?
