Allergies or something serious?

Patient: The back of my neck has been getting shocks for the past month and it’s been happening once a week or twice a week. Also I feel pressure on my face around the nose and eyes around the same time and my head hurts a little too. I’m worried it’s dangerous. Could it be allergies or sinuses or something dangerous?

Symptoms: Pressure on face , minor headaches, shocks on back of neck that last a couple seconds
