Perhaps you've had headaches that caused you to experience nausea and vomiting, and then seek refuge in a darkened area until the pain eases. If this is the case for you, then you could be suffering from migraine headaches. 

They may last for one hour to several days. The only way to be sure that you are suffering from headaches like these is to be identified by a competent medical specialist. The first thing to do is talk to your best migraine doctor. 

A quarter of people have migraines, and your physician is likely to have some knowledge about them. If your doctor seems to be dismissive regarding your symptoms and doesn't believe that he is able to find the root of your issue it is best to request him to send you to specialists.

If the doctor is not an appropriate specialist, consult your medical insurance provider. They'll be aware of several trustworthy ones. If they're unable to accomplish this, consult your local board or browse the web for headache specialists and specialists in headaches themselves.

Make sure to talk to your family and friends. There is a good chance that you know someone who suffers from migraines. They may have the doctor they love. 

Another option is to ask to be referred and urgently locate an expert who can assist you. When you do find an expert, you must make sure that they're competent to assist you.
