Do you get an allergic rash from the pads? I don't think the pads are causing sinus allergic reactions. I have bad allergies as well. And I do notice that I get them worse when I am about to get my period. I really just thought it might be that when I get my period my immune system goes down a bit. I really don't know. But if you aren't getting an allergic rash I don't think it is the pad that causes it.
