I have year-round, almost daily allergy and sinus issues, which quite often lead to migraine attacks. PCP's and ENT's have not been able to help me; they just give me medicine and send me on my way, like most doctors these days tend to do. I have tried taking both OTC and prescription allergy and sinus medicines when I feel a migraine coming on, and even tried taking a daily allergy med to try to help prevent them or lessen the frequency - all to no avail. I read that if you have year-round allergies, it's recommended to use a steroidal nasal spray (such as Nasacort) daily for best results, as they are more effective and "reach further," so to speak. I am willing to try it, hoping that if I can combat the allergies/sinus pain, maybe I will get fewer attacks or less severe ones. I was just curious as to whether anyone has tried using the steroidal nasal sprays as a possible migraine preventative/treatment, and if so, was it a success in any way?
