Persistent headache after Mohs surgery on nose.

It's been a three days since Mohs surgery on my left side of the nose. They did not do a skin graph, but closed the would with sutures, I'd say it's about an inch long. I've had a persistent headache, and headache remedies just take the edge off. It's not extreme, but just there, nagging. For the first two days, I had taken Extra Strength Tylenol, and switched to Ibuprofen today, yet the dull ache is still present. Is this normal?
