Dr,
I am 37 year old male, 6ft tall and weights 74kg. Over last few years i have been seeing gradual loss of fat/muscle mass especially on my hands and feet. Some visible shrinking is also observed on the arms and lower leg mass. (Attached are some pictures). I can walk; perform all other functions as of now. Certain movements do cause a snapping sound at wrist and also at times on the hip, knee, shoulder, elbow joints as if muscles are wasted and tendons are snapping. I get some muscle twitching at times on feet and sometimes on arms. But not for very long, like 3-4 twitches. Sleeping on certain positions gets me cramps on hand (up to fingers) at times.

I did consult a neurologist in my area and he did EMG/NCV tests which returned normal results. Next was an MRI and that too was normal except for a tiny lesion he found on one of the D blocks which as per his diagnosis is not possibly the cause for any muscle wasting is quite a small one. All other clinical tests done (kidney, liver, serum b12, thyroid etc) are normal.
Please help me with your experience with such symptoms.
Regards
Bip
