when I read your post, I thought I was talking about myself as for the past 8 years no one seems to know the underlying cause of my signs and symptoms which are compatible to your friend's signs. I've seen Neurologists, Neuro Surgeons, Orthopedics, Orthopedic Surgeons, and Foot and Ankle Surgeon. And through the course of 8 years, I had MRI's done [including my Brain - Cervical Spine - Thoracic Spine - Lumbar Spine, and Pelvis (some of which were with and without contrast)]; I even had MRV done. And, I got tested for Lyme Disease multiple times; and had Nerve Conduction Tests twice. All Doctors agree that they can't figure out the underlying cause of my signs and symptoms. I remeber when one of my Neurologists prescribed for a course Prednisone (20 m, I thought I got healed beacuse I regained my normal function again as I started to walk normally and wife couldn't keep with me. However, after the course of Prednisone was over, I was contained by my signs and symptoms again. Last night, I've come accross the possibility of a "Virus" or perhaps "Virus(es)" causing a foot to drop; and so I started to search online; and, I found an "Abstract" concerning "The Herpes Zoster Virus" stating that such Virus is "A RARE BUT POTENTIAL CAUSE OF ACUTE MOTOR WEAKNESS," and the abstract included two people who just so happened to have a "Right Foot Drop." Today, I sent message my Foot and Ankle Doctor message of containing the link of the abstract, to which he replied:
"REALLY VERY INTERESTING."
I wrote him back this question:
"Is there a collective blood test I can get to check for all potential viruses that I may have, which could be causing my condition?
I'm still waiting for him to reply.
Be that as it may, the following is the Abstract which I cut-and-pasted; and for the record, I've included the link of the Abstract at the end:
The herpes zoster virus is a rare but potential cause of acute motor weakness.
This article describes 2 patients with drop foot secondary to an infection of varicella zoster who were incorrectly referred to an orthopedic clinic from their general practitioners >>
>> The first patient was a 74-year-old man who presented with:
1) Weakness in the Right Foot, and
2) a Vesicular Rash.
The pattern of disease supported the clinical diagnosis of shingles affecting "The L5 motor," and "Sensory Division."
No investigation was required, and the patient was treated with a "Foot Drop Splint."
>> The second patient was a 71-year-old man who presented with:
1) Right Leg Foot Weakness, and
2) a Vesicular Rash affecting his "Right Buttock," and "Posterior Right Thigh."
Lumbar Magnetic Resonance EXCLUDED a "Stenotic Lesion;" and, "Electrophysiological Studies" SUPPORTED the diagnosis of a "Lower Motor Neuron Lesion."
THE PATIENT WAS TREATED WITH:
1) A 1-WEEK COURSE OF "ACYCLOVIR," AND
2) A "FOOT DROP SPLINT."
The correct diagnosis will aid in correct referral and will prompt management, which will potentially provide a faster and better outcome for the patient.
