Intense pain behind eyebrow (Plane ride)?

Alright today i was on the trip back from Disney World to my home town by way of plane. The trip went smoothly until it came time for the landing. As soon as the pilot turned on the fasten seatbelt sign, i recieved a sharp pain behind my left eyebrow that would not go away, and soon my left ear became blocked so i could bearly hear. Its now hours later and i got the hearing back in my ear but i still have a mild pain in my head. Is this serious?
