I have been experiencing pain in a specific spot on the left side of my head, just above my left ear. The pain is triggered by rubbing or touching the area with my hand or towel, and it also occurs when I cough. Initially, the pain was mild and occurred mainly with these triggers, but since yesterday, it has become constant. The pain is now radiating toward my left ear and also toward my left eye. I also experienced tingling in the same area yesterday. The pain is still mild but has remained persistent since yesterday
