Joe,

I had the amyloid biopsy too...a mini tummy liposuction. It is not painful. Mine was negative. Results came in about 2 weeks.

I also recently had a muscle biopsy, that is being analyzed....all I know is it shows myopathy in my bicep, which is quite proximal and far away from the feet and the hands, kind of surprising. It appears neurogenic...so the neuropathy is essentially causing the myopathy, which happens, but usually not so close to the trunk. They also stained the muscle for amyloid...negative. They are deciding if I have anterior horn cell disease of some kind or just rather profound generalized small fiber potentially genetic. I got prelim results in 2 weeks...now waiting for more final results.

Hope that helps.
