It sounds a lot like you are having migraines. Migraine
headaches are a severe type of headache that usually cause pulsating pain in the head and that are very often associated with other symptoms, such as blurry vision or changes in the vision, dizziness, sensitivity to light, and nausea or vomiting
. The fact that your headaches are so closely associated with a sensation of strong nausea makes me think that this is probably what you have!
I suggest that you go see your primary care doctor
to discuss these headaches, especially if they are very strong or if they are at all interfering with your life. Most of the time, frequent migraines will require taking a daily controller medication, or prophylactic medication. These medications are taken every day regardless of whether or not you are having headache, and they working by preventing the headaches. There are numerous controller medications that can be used to treat migraine headaches, and your doctor will be able to discuss the risks and benefits of each one.
Together you will be able to come up with a plan to reduce the severity and frequency of your headaches so that you can have less disruptions in your life!
