Hi Dear .
As per your query you have lightheadedness
. Well there can be many reasons for symptoms you mention in query like benign paroxysmal positional vertigo , Vertigo may also be caused by inflammation within the inner ear sometimes due to infection , meniere's disease , acoustic neuroma
, sinusitis and multiple sclerosis .Sometimes there are simple reasons like low blood sugar
or iron level and anxiety are also responsible , but there can be some serious reasons like stroke is also possible . I suggest you to consult with ENT specialist
for proper checkup . Doctor may order certain test like CT scan , MRI , blood test
, audiometery test and rotatory chair test . Doctor may prescribe ant emetic drug , sedatives , antibiotics and some ear aid and recommend vestibular therapy . For now avoid bending foreword , drink green tea thrice a day and do light exercises daily . Doctor may also refer you to cardiologist for heart problem .
Hope your concern has been resolved.
Get Well Soon.
