One of my neighbors whom I have known since her childhood has had both legs amputated due to infections from diabetes..She does very well on two prosthetics
She had physical therapy both times to help her adjust..Both prosthetics feel and look very natural
She is an amazing person and has been such a blessing to so many people with her great faith and wonderful personality..She was given her brothers perfectly matched kidney 20 years ago when one after another of hers failed..Sadly that kidney is now failing as quickly as her eyesight...
Best of luck to your friend
