Hi, I Suffer With Sinus Problems Now And Then But

Hi,
I suffer with sinus problems now and then but nothing dramatic. However I had a sinus infection when going on holiday 4 weeks ago and the pressure on my sinus when landing was horrific. The infection has only just worn off but I am now left with a sinus headache which comes on at the same time every day, is this normal or do I see my GP?
Thanks
Laura
