Headaches: Headaches including Migraine equivalents are often hard to diagnose the cause, especially over the computer. There are multiple factors that can be involved, so best advice for you is to see your doctor and get the full History and physical done, so the best and most accurate cause can be found, to assure the best treatment. Good Luck!
