What Causes Sudden Loss Of Balance And Dizziness While Working?
Inner ear most likely origin.
Detailed Answer:
I read your question carefully and I understand your concern.
Looking at the description of your symptoms I would say that the most probable cause for it would be an inner ear related issue, like benign paroxysmal positional vertigo, labyrinthitis, vestibular neuronitis etc. The symptoms look typical, especially with head movement provoking them. If you tend to go on the left that side should be affected (the healthy side pushes towards the affected one). In terms of treatment to alleviate the symptoms meclizine or betahistine are the most commonly used options.
Now regarding other possibilities, the one which is always feared is a stroke involving you posterior brain areas which together with the inner ear are responsible for balance. It is not as common as inner ear causes and would say that is not that likely in your young age. Furthermore there usually are other manifestations such as headache, double vision, weakness or sensation alterations in the face and limbs, slurred speech etc.
So while you can still make that trip to ER to check for neurological signs you might have missed, or even ear related ones such as infection, I would say that the ear should be the culprit. It is very bothersome (I can relate as I went through your exact situation myself this January) but usually gradually subsides over the coming weeks.
I remain at your disposal for other questions.
