Hi, I understand your concern. Your symptoms of dizziness, shakes, hot flushes, headaches, blurred vision, aching legs, light headed if started the last few days are indicative for acute viral infection with generalized symptoms. However, other factors should be considered including: - meds you might have started recently? - thyroid problems: get a thyroid function test done - eye problems to rule out through a specialized eye examination. So, I advise to: - increase fluids intake (especially plain water with oral rehydration salts) - take anti-inflammatory meds like paracetamol or ibuprofen - get more rest - start magnesium supplement containing vit.B complex If still no improvement, should see your physician for more specialized examination and treatment. Wish fast recovery.
