Hi,
Noted the history about your friend having
hypertension, fall from a chair, normal
CT scan but has
nerve like pains in leg and knee.
This may well be related to fall as he might have sustained
injury to the lower spine.
This can be diagnosed by the following ways.
Take him to the regular Physician for checkup to have a preliminary diagnosis.
Can get a referral to a Specialist like Neurosurgeon.
MRI of the lower spine.
Nerve conduction studies.
Control of hypertension.
Get started on proper nerve medications.
Surgery if there is any
slipped disc or so that is causing nerve compression.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
