I have some problems with dizzy spell and I am not always sure what causes it. If my anxiety is running high I may feel a bit dizzy but I know my pulse rate is up and I am just in increased anxiety mode.
I use antivert if I feel dizzy after taking my meds.
I am glad to hear your physician is doing a CT of your head. Try to stay in the moment and do not over think the test. You will make it through. Prayers and hugs to you.
I mentioned in my post Antivert is the drug of choice OTC for dizziness. Dramamine may also be used. However I would see you physician if this continues to be a problem for you as other illness have dizziness as a sx.
