Between us, we convey two views to persistent sickness: private expertise of lengthy COVID, and medical and analysis expertise in continual sickness rehabilitation.
Each have taught us the identical factor: when signs are actual, disabling and tough to clarify, sufferers want greater than reassurance that assessments are regular. They have to be believed, assessed rigorously and provided methods to make sense of what’s occurring of their our bodies.
One in all us, Sarahjane, is aware of this personally. Earlier than growing lengthy COVID, she was match and wholesome. As a professor of well being and bodily exercise, her life was devoted to serving to folks perceive and enhance their well being.
Then she grew to become unwell.

For 2 years, she might barely perform. At her worst, she couldn’t stand for quite a lot of minutes. On a regular basis life shrank round extreme and horrifying signs. Like many individuals residing with lengthy COVID, myalgic encephalomyelitis/continual fatigue syndrome, typically shortened to ME/CFS, continual ache and different persistent situations, she looked for solutions. There have been scans, assessments and consultations. Time and again, outcomes got here again clear. But the signs remained.
That mismatch might be devastating. When the physique feels as whether it is screaming for assist, regular take a look at outcomes can really feel much less like reassurance and extra like abandonment. The extra medication struggles to clarify signs, the extra sufferers could concern being disbelieved.
Nervous system schooling
For many years, folks with poorly understood situations have been instructed their signs are “all of their head”. That phrase has accomplished huge hurt. It has been used to dismiss ache, fatigue, dizziness, breathlessness, weak point, sensory sensitivity and cognitive signs which can be actual and disabling.
However fashionable science asks us to assume extra rigorously. The nervous system is a part of the physique. The mind is a bodily organ. It interacts with immunity, hormones, respiration, cardiovascular management, ache processing and the stress response. Once we speak in regards to the nervous system, we’re speaking about biology.
That is related to lengthy COVID as a result of some folks develop signs involving the autonomic nervous system. This regulates capabilities equivalent to coronary heart price, blood strain, respiration, digestion and sweating. When it’s not working correctly, folks can expertise dizziness, palpitations, breathlessness, faintness, train intolerance and mind fog.
Lengthy COVID and ME/CFS are complicated and various situations. Some folks could have organ injury, autonomic dysfunction, immune modifications or post-exertional malaise, when signs worsen after even minimal bodily or psychological exercise. Different causes and processes within the physique are nonetheless being investigated. Medical evaluation stays important when signs are new, altering or extreme.
Inside that wider image, nervous system regulation could also be one a part of restoration for some folks. After sickness, damage or extended bodily stress, the programs that detect menace and defend us can develop into extra delicate. The physique could stay on excessive alert after the unique hazard has handed or decreased.
One solution to perceive that is to think about a house alarm system. A well-calibrated alarm responds to an actual intruder. A hypersensitive alarm goes off when wind strikes a department towards the window. The sound is actual. The misery is actual. The issue is the edge.
For Sarahjane, this helped. It didn’t make her signs much less actual. It made them much less horrifying. As a substitute of combating every symptom in isolation, she started to know how her physique’s protecting programs may be contributing to the general sample. She might work along with her physique’s limits somewhat than pushing towards them.
This understanding is central to Second Arrow: Reworking Lengthy COVID, a programme we developed to assist folks residing with persistent signs. In a small early research, individuals realized how the mind and nervous system can contribute to ongoing signs, and got sensible instruments to handle every day life with lengthy COVID.
Individuals described the pressure of residing with signs they might not clarify and that medication had not but accounted for. In addition they described the aid of being provided a framework that took their signs severely whereas giving them sensible methods to maneuver ahead. One participant mentioned the course “gave us hope” and “confirmed us a path”.
For somebody residing with persistent signs, hope shouldn’t be a small factor. Nevertheless it needs to be sincere hope: no promise of remedy, no suggestion that restoration will depend on constructive considering, only a cautious approach of creating sickness really feel much less horrifying and fewer inconceivable to reside with.
This method shouldn’t be a remedy. It’s not an alternative choice to medical investigation, prognosis, pacing, medicine, social assist or specialist care. It ought to by no means be used to inform folks to push by signs. For folks with post-exertional malaise, doing an excessive amount of could make signs worse, generally severely. Any rehabilitation method should respect particular person power limits.
Used rigorously, nonetheless, nervous system schooling might be one rehabilitative instrument. Restoration could contain body-based approaches equivalent to respiration, rest, pacing, relaxation, symptom monitoring and thoroughly tolerated motion. It might additionally contain methods that work by consideration, interpretation, concern, planning and confidence. These approaches recognise that ideas, feelings, immune responses, ache pathways and bodily signs are a part of one organic system.

Not all in your head
Sufferers are proper to be cautious when explanations contain the mind or nervous system. Too many individuals have been dismissed, disbelieved or instructed to train their approach out of sickness.
However rejecting brain-body science altogether leaves sufferers poorly served. The nervous system is a part of the physique. It may be injured, sensitised, overloaded and, in some circumstances, supported to alter.
Persistent signs are actual, organic and infrequently disabling. For some folks, understanding the nervous system can supply a sensible route in direction of managing signs and enhancing high quality of life.
Individuals residing with lengthy COVID, ME/CFS and different persistent sicknesses don’t want one other argument about whether or not their sickness is bodily or psychological. They want cautious evaluation, respect, assist, analysis and therapy approaches which can be sincere about uncertainty.
Most of all, they want healthcare that doesn’t quit when the assessments come again clear.
