Doctor,
I have been seeing a neuroloist at the University of Michigan Ann Arbor, who is stumped
My symptoms began a year and a half ago when the 4th and 5th digits of my right hand got "stuck" gripping a knife. Since then, my symptoms have progressed to include severe weakness and atrophy of all the intrinsic muscles of the right hand, with some weakness and atrophy in the forearm. (I have one lb of pinch strength in my right hand, compared to 25+ lbs in the left.) The extensors are not as severely affected (my pinky is the only finger not strong enough to type with)
Attempts at diagnosis originally focused on the right arm/shoulder, with EMG's, MRI's and X-rays ruling out slipped discs, carpal tunnel (there was no significant nerve velocity change across my elbow) tumors, etc.
On July 3rd, my 1st appointment at U of M, the physical exam and EMG confirmed early symptoms in my left anterior tibialis. Which led us to consider more systemic problems. I have since had numerous tests, including B-12, folate, GM-1 antibody, Survival Motor Neuron Gene, CK, C-reactive protein, Parathyroid, and numerous others. These tests were from blood samples, and a lumbar puncture. So far, everything has come back normal.
With the exception of the weakness (and a little healthy fear) I feel great. I've lost a little weight, but I've been working at it and it's been slow. I'm in no pain, but I do have occasional numbness, very rarely a little twitching, and occasionally if I extend or contract certain muscles in my feet and legs (primarily the left leg) I will experience a "stuck" feeling comparable to that which was my first symptom in my right hand.
I get the impression that I am not fitting into any category, because my symptoms and clinical results don't track. My symptoms look to me just like multi-focal motor neuropathy, but my EMG's, according to my doctor, look more like Motor Neuron disease. The lack of pain also seems significant.
My neurologist at U of M said the only things we can do at this point are either wait for something new to develop (my next appointment is in December) or get a second opinion. I would prefer not to wait--who knows when the muscles of my hand will become to far gone to recover even if we find a treatment.
I would appreciate any input,
Pam
