Hi. I have a headaches that started a couple years ago, but at first was very small and only occurred every few weeks. Now it s much stronger and almost constant, though varies in strength. It s on the right side only and felt in my eye, cheek bone, temple, sinus , and a little in the upper neck . My right cheek usually feels puffy and tight. When it gets really bad, my eye gets bloodshot and my right eyelid tends to be more closed than the left one. Ideas?
