The 57-year-old has chronic arthritis in both hands and is also struggling to come to terms with the death of his partner of 11 years, Emma Wilson, earlier this month.
But in order to receive the new Employment and Support Allowance, Mr Cann has been ordered to undergo stringent medical tests which he believes will be a waste of time and money.
An assessment four years ago before he was confined to a wheelchair found he was unfit to work.
Mr Cann, of Cauldon Road, Shelton, said: “It seems a pointless task to me because I am already classed as a triple amputee by social services. It is a waste of time.
“Four years ago I was unfit to work and my health has deteriorated a lot since then. Even if I could get down there they will take one look at me and say I am unfit for work.
“I am very obviously disabled so I don’t see what tests they have to do. They are just making me jump through hoops.”
The Department of Works and Pensions (DWP) made an appointment for him at Atos Healthcare Stoke Assessment Centre on Festival Park for August 24 – just 15 days after he had his right leg amputated at the University Hospital of North Staffordshire.
His left leg was removed in January after he developed ulcers.
If he is deemed fit to work, Mr Cann, who was diagnosed with diabetes six years ago, says he faces losing around £600 a month in benefits.
Mr Cann, who spent 30 years working in the fast food industry, said: “I am housebound and on my own. They expect me to get a taxi which will cost me £10 each way but I can’t really do that without help.
