Thank you for your question to HCM.
The symptoms you have described can be due to cervical spine
stenosis that leads to weakness of the grip, finger numbness
and leg symptoms like stiffness
, change in walking pattern with frequent falls and leg numbness
. For evlauation of this you will need clinical examination and MRI of the cervical spine.
At this point you can keep your appointment to see the neurologist
however if the weakness is getting worse try to schedule an earlier appointment or go to the ER if it is emergency.
Hope this is helpful. I would be happy to answer any questions.
