Hi and welcome to Healthcare Magic. Thanks for your question...
Although light-headedness can be one of the physical symptoms of anxiety
, yet, severe and persistent light-headedness definitely needs further evaluation. It can be due to a variety of medical causes e.g. abnormal blood sugar, elevated blood pressure, ear problems, etc. You also need to elaborate more on the nature and duration of your anxiety symptoms to see if the lightheadedness
could be related to it.
Since you have mentioned that your light-headedness has a postural variation (i.e. worse on standing and better on lying down) it is likely to be due to 'vertigo' (which is a problem related to the balancing apparatus in our body)
I would advice that you need to consult your doctor and have a detailed evaluation in order to find a cause and then appropriately treat your problem.
All the best.
