Doctors are treating a patient with dermatillianomania for months at a time and are reluctant to prescribe medication, because it can worsen symptoms.
The NHS has also stopped some treatments for people who have been diagnosed with the condition.
They are being forced to use their own treatments.
Dermatillomaniacs are not the only group suffering from the condition, with many people believing they have it too.
They also say it has led to a rise in infections.
The patient is part of a growing group of sufferers with the illness, which affects up to 2.5 million people worldwide.
The number of new cases of the condition in the UK has risen by 100% since last year, according to NHS figures.
Many doctors and patients believe the treatment is inadequate and some have resorted to using antibiotics.
Dr Mark McPherson, who treats patients with the disorder at Liverpool’s King’s College Hospital, said: ‘It is very difficult for me to prescribe [medication].
It can cause infection and the need for hospitalisation.’
He said he would prescribe the drug at least once a week.
‘I have a patient who has a history of infections and has been in intensive care for two weeks,’ he said.
‘He is very sensitive to antibiotics, and we have tried everything we can.’
He is a very sensitive person, he’s got an allergy to the drug and we don’t think it will work, so we don.
‘The doctor has had to prescribe it four times a day.
It’s very difficult, but we have to do what we have got to do.
‘It’s not a good idea to start prescribing antibiotics in patients with this condition.’
The patient has had the drug for eight weeks and we do not prescribe it to people who are taking antibiotics.’
He added: ‘The person who has had it for two years is a really good example of this, because we’ve had two weeks without him taking it.’
The patient had been taking the drug to help with pain after a stroke.
The condition has a range of symptoms including muscle spasms, fatigue and depression, but symptoms can last for weeks.
The majority of sufferer are between the ages of 18 and 64, with women particularly vulnerable.
They can also have anemia, depression and heart problems.
The average age of a sufferer is 65, and the majority have had a stroke, but the condition is not always caused by one.
About half of the people in the NHS are considered to have dermatillomania.
The symptoms include a persistent, intense desire for contact with the skin, the inability to concentrate, difficulty with breathing and a loss of coordination.
They often start within days of being diagnosed, and some can be self-limiting.
It is not known why some people develop the condition; most sufferers believe it is related to a genetic predisposition.
The first cases were recorded in the late 1800s, and cases increased during the Second World War.
About 3,000 cases were diagnosed in the first half of this century, but since then the figure has fallen.
More than 4,000 patients have been treated, although only a small number have survived the disease.
Dr McPhersons work involves assessing patients for signs of skin problems, which can include itchiness and dry skin, as well as infections and infections in the joints.
The problem can also lead to skin cancer.
He said: [It is] quite a difficult condition to treat, but it is a difficult diagnosis to make.’
We do everything we possibly can to try and keep our patients as comfortable as possible.’
There is a lot of research going on to try to understand what is happening.
‘Some of the patients have also been given steroids for a very short period of time to try prevent the infection from developing further.’
The condition can affect people from all ages, with some developing the condition while pregnant or after a heart attack.
