Mild Pain Back Left Head

Patient: I suffer with nasal allergies. Last week I noticed that whenever I get a discomfort in my left nostril (middle turbinate) I would feel a pulsating mild pain at the back of my head near the hallow region on the same left side. This week there’s no pulsating pain but a very mild pain below the region that was hurting. Feel the same mild pain if I pull my hair when combing it there too. Don’t know if what I’m feeling is connected to my nostril.Thank you

Symptoms: Mild sudden pain
