Hi I am a registered nurse. This evening my boyfriend reported to me that he is experiencing dizziness, even while laying down, along with excessive BL feet diaphoresis. I took his vitals: BP: 122/60, SPO2: 97%RA, pulse: 72, temp: 98.8, respirations: 16. He has had ongoing issues with anxiety and also reports that he feels some anxiety at present but not severe and he is not experiencing a panic attack. What could be the cause of this dizziness? He said he doesnt feel himself and he does not regularly experience dizziness so it is a concern to him. I advised him to increase his fluids and he has been drinking plenty of fluids for the past few hours.
