I am a 43 female, 67kgs, 176cm height, two years ago I had a episode of vertigo and spent two days in hospital. I still feel light headed/off balance, i do have low blood pressure, I dont know if its stress related, i suffer from regular headaches and have had cat scans and all clear, but why is it continuing? I feel like I am on a wharf, and gripping on with my toes so I dont loose balance?
