I have had this experience. I told the doctor my symptoms, when this flare first started. that is when he did the blood work that got the ana thing positive.
Others may have a good point too. Low blood pressure.
Mine also happens with diarreah. I can't stand up straight and have to hold onto the wall to get to the bathroom, dizzy, weak, and unbalanced. Horrible feelings.
I agree that you should get to the doctor with these symptoms. the first doctor I went to, prescribed meclazine for three times a day, and said it was vertigo. The meclazine helps but does not eliminate the symptoms. they still happen sometimes.
Hope that things will get better for you Superwoman.
