Younger people who think they are “invincible” need to be aware of the shocking life-changing reality of long Covid, according to health professionals who are living with the condition.

Painful palpitations, chronic diarrhoea, brain fog and only being able to walk very short distances are among symptoms described to MPs by three people in their 30s.

Long Covid, also known as post-Covid syndrome, is used to describe the effects of Covid-19 that continue for weeks or months beyond the initial illness.

Speaking at the All-Party Parliamentary Group (APPG) on Coronavirus, Dr Nathalie MacDermott, 38, said neurologists believe Covid has damaged her spinal cord and she can only walk about 200 metres without some form of assistance.

She said the damage has affected her bladder and bowel too, causing urinary tract infections, and she gets pain in her arms and has weakness in her grip.

Dr MacDermott, a clinical doctor sub-specialising in paediatric infectious diseases in the NHS, told MPs there needs to be “better recognition” from employers that long Covid is a “genuine condition” and that people may need to be off work for a significant period of time.

She added: “And I think we need better recognition in the public, particularly the younger public who think that they’re invincible.

“I’m 38 and I wonder if I’ll ever be able to walk properly without crutches again. Will this continue to get worse? Will I end up in a wheelchair?”

Dr Linn Jarte, a 33-year-old anaesthetist, said even just taking a couple of steps would make her feel “absolutely horrendous” at the start of her experience with long Covid.

“I felt as if my whole body was just filled with lead, but at the same time I had this sort of painful burning situation, and it also made my heart rate just shoot through the roof,” she said, adding that she had painful pins and needles.

Dr Jarte was affected by brain fog, describing it as a “thick cloud that just fills the brain”, adding: “I just stopped being able to think.”

She said she could not tolerate stimulation, with even soft music being too much for her.

“I spent a lot of time during those first few months when I was the sickest just sort of staring into thin air,” she said.

Dr Jarte said that before this happened to her, she was very fit and active.

Geraint Jones, 30, an advanced pharmacist specialising in HIV and homecare, described “crying on the floor” of his living room after medics were unable to figure out what was wrong with him.

He told MPs that he suffered from chronic diarrhoea and abdominal pain for seven or eight hours per day at one point – a symptom which went on for 14 or 15 weeks.

Mr Jones said this continues to be an ongoing issue, adding that he has also been left with brain fog where he is unable to recall the most basic of words or phrases.

He said he also has tinnitus in one ear and painful palpitations.

The work lives of all three long Covid sufferers have been impacted, with Dr MacDermott telling MPs she has been able to work from home in her academic role but does not know how she will return to clinical work.

“There will need to be quite significant modifications in place for me to be able to be on the wards,” she said.

Dr Jarte said she has been unable to work at all since she became ill, due to physically not being able to and also the brain fog.

Mr Jones said he worked from home from July to September “just out of stubbornness” and a desire to keep going, but he added: “I woke up one morning in September and I just thought, ‘How long can I live like this? How long can I sustain this for?'”

He said he has been off work since undergoing a number of investigations, but medics seem unable to determine the cause of his multiple and ongoing symptoms.

Mr Jones said he does not know if he has the physical and mental capacity to be safe to practise as a pharmacist at the moment.

“Which is unfortunate because I love my job and I want to get back to helping my colleagues during these difficult times really, but I just physically can’t do it at the moment,” he said.

Danny Altmann, professor of immunology at Imperial College London, told MPs Britain probably has more than 300,000 cases of long Covid.

He said it is a case of “Russian roulette” because people do not know whether they are going to be one of the people who is better in two weeks or one of the people who is going to be on crutches or in a wheelchair “for months or years or forever”.

Prof Altmann said: “How many of us want to take that risk?”
