Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, we should rule out brain any
spinal cord related diseases first because
fainting attack, loss of balance, lose of strength in lower limbs etc are commonly seen with brain and spinal cord diseases.
So
consult neurologist and get done clinical examination, MRI brain and spine.
If all these are normal then no need to worry much.
Sometimes,
stress and
anxiety can also cause similar symptoms.
So avoid stress and tension, be relax and calm.
Don't worry, you will be alright. But first rule out brain and spine pathology.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
