What causes headaches and nausea
You need to note that there are numerous possible causes which could result in both headaches and nausea. There is no possible way to diagnose your condition over the internet. I would strongly advise you to please pay a visit to your family physician who can then offer advice after a thorough check up. Just some of the various causes would include pregnancy in woman or pre-menopausal symptoms. These two symptoms are also commonly seen in cases of caffeine withdrawal. You might experience such symptoms after a long run or running in the afternoon. In rare cases, it could result from excessive time spent in front of your monitor (this would be particular true in case of older model computer monitors).
