I am hoping someone can tell me what this is. For the past 6 days I keep getting left sided head pain.(whole side) The strange part is, it only lasts 20 seconds to 2 minutes. This happens 15-20 times a day. I also have a mild cramping sensation in the back of my neck. The cramping only happens a few times a day. For 2 different days I had a headache all day, with these my ears, eyes and teeth hurt. Any info would be greatly appreciated. This is driving me nuts.
