For the past 3 months, I have been experiencing muscle twitching in my arms and legs...now I am experiencing progressive muscle wasting. I have had all sorts of blood tests run from Thyroid to HIV. All tests came back negative. I have had a MRI, EMG, and that came back showing nothing. At this point, my doctor seems to think that some virus may be causing my muscles to waste. I am scheduled for a muscle biopsy in December. I want to know if there are any types of viruses that can affect the muscles...if so, are the results of wasting reversable...I'm pretty sure it's not HIV...but when I do a search on the web for muscle wasting...that's all that seems to come up. I've had 3 HIV tests and they've all come back negative. Also Lou Gerigh's(sp) disease was also ruled out. I'm getting scared now...PLEASE HELP!!!
I think that the muscle biopsy is the important test here, this should
identify the exact pathological process underlying this wasting problem.
there are a number of muscle idseases which can present like this,
It is reassuring that the most serious diagnosis (ALS) is excluded.
primary viral infection is an unusual cause of musclw wasting, HIV is
the best known but it is also described in some influenza viruses,
coxackie virus, HLTV 1, and hepatitis C virus infections.
At this point i would still think viruses may be low onnthe list of
probabilities and would look to the muscle biopsy as the key test.
