I'm experiencing lightheadedness, trouble concentrating, nausea, when i stand or sit, but feel better after laying down should I be concerned?

Many reasons: There can be many reasons for this. A common reason includes orthostatic hypotension from dehydration, in which case adequate hydration and getting up slowly and pausing for 15-30 seconds before walking may help. Another reason can be new medications. If this persists or gets worse, you should see your PCP. Further reading: http://www.nlm.nih.gov/medlineplus/dizzinessandvertigo.html ...Read more

Also, er doctors (like any of us) can be wrong. If you're concerned, return to er for a recheck. ...Read more
