I got dizzy sitting on the couch not bad and no other problems. what do you think? thank you?

I’m wondering if you are dehydrated, feeling anxious, have palpitations or other heart irregularities, have an inner ear infection or even just ear congestion, allergies. The differential of mild dizziness is really long. If it gets worse or if it does not go away in a day or so, consider a visit with your primary care doctor for further evaluation.
