Hi,
Welcome to Health Care Magic,
I am Dr.Naveed Ullah khan,
I have read your question in detail and will try to help you in the best way possible.
It could be because of multiple reasin one of which is what ur doctor said mught be a problem in the brain like a
stroke. That would need a CT or
MRI to confirm. It can also be due to problems in the
spinal cord. Also infections can cause this peoblem. Some autoimmune conditions. To find out i would like to get a detailed history. And a full nervous system exam. Do some
nerve conduction studies and also fo an
electromyography to find out if the problem is in the nerves or the muscles.
I hope this answered all your queries, if you have more queries,I will be happy to answer.
Wish you the best of health.
Regards.
Dr.Naveed Ullah Khan.
