I also get them a day or two before rain or a snowfall. My daughter does also. Ours are sinus headaches hurt like hell. We get them in different spots, hers is forhead between the eye's and mine is usually above the eyes, from there they go out to the whole head. Those mediy pot rinses help a bit if you do them lots. But once I feel it coming on it advil cold and sinus is the only one that works for us. Take as soon as you feel it and every 4 hrs or so. It seems to help on most of them but not all.
good luck
