I had a bad dizzy/light headed experience today, for the first time ever. I was having eyes tested. Had 4 of the tests. Looking at red house each eye. Then air puffed onto eye. Had to stop. Hate it. I jump 6ft. Then lights flash, say number you see, each eye. I then had to move chairs. I had to pick my bag up and as I placed it on the floor and stop up, I nearly fell, fell onto wall, grabbed back of chair and my legs went to jelly, head was swimming, eyes were dilated couldn t focus. My head was wobbling. I was shaking and v. pale apparently. It took over half an hr for me to cal. Down. My husband is v worried. Had loads of stress this yr. I ve got bipolar and under active thyroid. I take meds for both. Sodium Valproate, sertraline. And LEVOTHYROXINE. I slept from 6-9 when home and my eyes still don t feel right. Feel swimmy can t focus that well. I m extremely tired and stressed anyway.
Hello 1 I understand your concern. In my opinion this is may be just from stress or orthostatic hypotension. I would recommend you measure your blood pressure during sitting position and 5 minutes after standing up position. If your blood pressure decreases more than 20mmHg for the systolic and 10mmHg for the diastolic it may be orthostatic hypotension. It is a common disorder affecting depressed persons, bipolar patients, also considering Valproate therapy.  If everything is all right, a blood cell count would be necessary to rule out anemia. Hope to have been helpful.
