### output:

Hello, Well, your symptoms unfortunately don't coalesce as described into a single entity but if there was more information as to your age, other health conditions you may already have been diagnosed with, medications you are taking, etc. and whether you've been THOROUGHLY examined by a doctor would help me better put your symptoms in line.  However, would first want to get a good history on how quickly these symptoms came on and if there's been any let-up.  Next, a physical examination to include blood pressure and then, laboratory testing to make sure you're not suffering from thyroid issues, diabetes, or chemical imbalances of some sort (B12, vitamin D, folate, electrolyte deficiencies).  If an MRI is being scheduled I'm thinking that they are trying to be sure that you do not have any types of tumors, aneurysms, or even congenital intracranial anomalies which by your symptoms doesn't seem to be the case.  Worry and anxiousness can also trigger these sorts of symptoms especially the tingling and floating sensations you mention.  Is there anything of a stressful nature in your life right now that you'd rather be WITHOUT because often times if you can identify such a thing or things, get rid of them (legally! HA!) these symptoms get a lot better?  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
