I have dizzy spells nausea and sore head on left side?

Troubling: These are troubling symptoms that require further evaluation sooner rather than later. There could be a myriad of causes for these symptoms. They need to be viewed in light of a good history and physical exam. I would strongly suggest a visit to your family doc or er for a complete evaluation asap...

Could be serious.: 42 year old female (or male), with onset of new headache, dizzy spells, nausea must be evaluated. If there is already a diagnosis of chronic headaches, or migraine that had been worked up in the past, then this may not be worrisome. That being said, even if chronic migraine present, a change in the pattern or frequency or type of ha needs a new eval. C your pcp and may refer u to neurologist.
