Severe headache over Right eyebrow. Do?

I get cold and sneezing frequently, once or  twice a week from the time I wake up till about noon. My doctor has diagnosed allergic rhinitis and using spray duonase which has improved my condition to the extent that I am almost not having any sneezing or cold. As per the suggestion by the doctor I have tapered my dosage as well. Now I have moved to pune from BLR for 10days and I'm staying in a hotel. I am experiencing severe pain over the right eyebrow in the morning 1or 2 hours after I wake up. I have taken plain water steam but it is not helping. I have been taking Saridon which seem to take me through the day but the same pain returns the next day. It has been happening for last 3 days.. I don't have any cold or running nose except watery right eye. Please suggest what should I do?
