Migrane headache or Sinus Headache

Hi  I started having "headaches" ie: Migranes/sinus headaches"  about a year ago.  I thought or still think they have something to do with the meds I take.  I have tried Imitex and it didn't help.  Now I take Frova, which helped at first but now it does nothing.  When all this started I was having the headaches about once a montn; and I'm talking BAD headaches enough to be hospitalized once.  Now, I'm having them about once a week.  I am so frustrated.  But, here's where I would like some input; I have frequent Sinus Infections aparently a side effect of Remicaide (an infusion I get for Crohn's every 6 weekds).  Could the sinus infections trigger the migranes.

Koko08 thanks for replying, it really does suck. I am having the same problem as you Sinus is triggering the migrane. I am having about 1 bad migrane a week. It takes me 3 days to get over it. I am just about ready to chop my head off! The only relief I am getting is to get a shot at dr office. That seems to break the headache but it will be right back in a week. What helps yours?
