One of my patients reversed his leg neuropathy and foot ulcers. He was numb/pain to the knee and had had the ulcer for 18 months and amputation was likely. It took five years but he has almost normal feet and legs now.
Another reversed his eye haemorrhages and maculopathy. From getting his eyes lasered every two months and a macular hole he has quiet eyes with reversing retinopathy and normal maculas. It took 18 months.
It can be done. Dr Bernstein was able to reverse his retinopathy, kidney damage, heart damage, and blood vessel calcification but could not reverse his droopy eye lids or foot deformities.
