Yes he has had EMGs for upper and lower limbs and they all show the neuropathy is not severe. Neurologist mentioned the punch biopsy test but thought since the results were not severe, he didn't want to put him through that. But I will mention it to the neurologist we are seeing in May. His whole body has had MRIs including cervical and lumbar spine. The imbalance (which causes some of the falls) has been linked to areas of his brain that have been damaged due to over 40 years of diabetes (sometimes not well controlled). But it's the strong legs one day and weak legs the next that is driving us crazy and no doctor so far can seem to explain. One doctor told us that the brain is like out space and what he has may not have been "discovered" yet. That's why I was asking if anyone else has this problem of waxing and waning of their muscles from day to day.
His hand sometimes shakes but we were told he has Parkinsonism which affects that.
Doesn't really have any issues with bowel/bladder.
Thank you for your thoughts on this.
