Myopathy Suspected, Biopsy Ordered

The title pretty much sums it up. 

On Friday I had my follow-up appointment with the neurologist who specializes in neuromuscular diseases.  My blood work was normal (i.e., no abnormal muscle enzymes), but my EMG had  abnormalities.  The EMG results suggest a possible myopathy, so the doctor wants to do a muscle biopsy to look for metabolic or mitochondrial myopathy. 

Here is the EMG summary:
1. Motor and sensory conductions of the right arm and right leg were normal.
2. EMG of the right arm, right leg, and right shoulder and hip girdle muscles showed minimal short duration units in proximal muscles of the leg > arm.  No fibs or positive sharp waves were observed.  EMG of the thoracic paraspinal also showed slightly more short duration units than expected without any abnormal spontaneous activities. 
Comments: Minimal amount of short duration units in proximal muscles of the legs > arms/paraspinal.  These findings are suggestive of possible underlying myopathy.  
I haven't scheduled my biopsy yet, but I plan to call on Monday to get an appointment.  I'll be getting the biopsy on my left arm.  I'm nervous because the doctor said the procedure will be very painful and I won't be able to use my arm to lift anything (including laundry) for two weeks.  Well, at least she's honest.

Update February 12:  I thought I'd explain the results a little better.  It's my understanding that there were abnormalities in all the muscles they tested but my legs and arms were the worst, with my legs showing even more abnormalities than my arms.

Our daughter(16) had her open muscle biopsy last year in office. They used a local.

I won't lie, she said she had to ask for more local, but she said in her opinion the EMG was far worse for her. Her EMG findings were similar to yours but found in all muscles.

They found a Mitochondrial myopathy(Depletion). Hang in there, and there are a couple of great groups on facebook where folks who are suspected and diagnosed all support one another.

Hope they find answers for you.

Best of luck Alyson. I hope the biopsy goes ok, and that they can help you with these issues : )

Hi Diane - Thanks for the post. I'm sorry that your daughter has to deal with all this. I guess I should have explained my results better in my post. They did find abnormalities in all my muscles. It's just that my legs were worse than everywhere else.

The EMG was pretty awful, so I hope I don't have to have another one for a long, LONG time. It's oddly comforting to hear that your daughter thought the EMG was worse than the biopsy. I'm hoping for the same.

Hi Treya - Thanks for the well wishes!

I hope the biopsy goes OK....are there some treatments that may help if indeed you do get diagnosed?

Hi upnorth - Thanks for the well wishes! I have no idea about treatments. I suppose it really depends on what they find in the biopsy. From what I've read, though, there don't seem to be many options.
