Thanks for writing to H.C.M. for yoyr query.
I have gone through your query regarding dizziness
and severe headache
. though you are in touch with your GP, but still weakness and unsteadyness are disturbing you. Your MRI
brain is normal. As you said that in acute attacks you feel difficulty in movement of legs due to weakness and appears as they are not as desired.
You also feels clicking sound during swallowing, but this is normal. Your history of ill ness reflects that your audiovestibular and neurological examination is must to pinpoint the diagnosis.
Your vestibular function tests are to be done so consult ENT doctor and neurologist
should examine the CNS and by the co-relation and interaction of these two your diagnosis may be made, and accordingly plan for treatment.
