I Was Born Into This

Classical Ehlers-Danlos Syndrome, a connective tissue disorder that affects every system in my body, has been present since birth. It took 45 years to get that confirmed on paper. I was adopted, and without a genetic family history, the diagnostic process stalled for over four and a half decades. By the time the diagnosis arrived in 2012, I had already accumulated roughly 343,000 dislocations and lived the majority of my adult life without any medical framework to make sense of what was happening to me.

The current count stands at approximately 360,000 lifetime dislocations and 3.56 million subluxations. Around 200 per day, every day since I was 10, ongoing. Every major joint: knees, shoulders, hips, toes, fingers, ribs, jaw.

Before All of This, I Had a Career

I spent years at PricewaterhouseCoopers as a Senior Technical Design Architect. I understood complex systems, interdependencies, failure modes. I was good at it.

Then my body became the most complex system I'd ever encountered, and the one I had the least control over.

That systems-thinking never left me. It's how I eventually built my way out.

The Pharmaceutical Years

From childhood onwards, pain management meant medication. I worked through almost every option available: paracetamol, codeine, dihydrocodeine, tramadol, buprenorphine, oxycontin, morphine, fentanyl, methadone escalating as each stopped working or the side effects became unmanageable.

By 2007, I had exhausted conventional treatment options. My body had developed dangerous tolerance levels. The escalation that followed was not a choice so much as a collapse of alternatives. At peak: fentanyl, methadone, morphine, OxyContin, buprenorphine, gabapentin, combined equivalent of approximately 4 grams of morphine per day. I was near-comatose around the clock. I lost years to it. I barely remember them.

I developed severe central sleep apnoea during this period. There was a 60% nightly risk of death in my sleep. I didn't know that figure at the time. I know it now.

My wife carried everything during those years. No family support. No reliable medical support. Just the two of us managing something that had no roadmap and no end in sight.

I was in a very dark place. I begged her to help me end my suffering.

2019: The Choice

In November 2019, the choice became binary: stop all pain medication, or likely not survive another year.

I also had a severe leg infection related to Classical Ehlers-Danlos Syndrome and Chronic Venous Insufficiency that wasn't responding to antibiotics. I was on an 800-calorie medically supervised diet. Everything was in crisis simultaneously.

I asked my pain management team at West Suffolk Hospital whether they knew of anyone who had successfully detoxed from high-dosage morphine at my level. They didn't.

They gave me autonomy to choose my own approach, warned me about the mental health implications, and I set myself one rule: reduce by no more than 10% every 14 days. No shortcuts.

The detox ran for 256 days. Continuous withdrawal symptoms, comparable to cold turkey heroin, for the entire duration. The first major reduction hit hard within days. My mental health hit its lowest point within the first four weeks. There were days I couldn't get out of bed. The temptation to take another pill was constant and logical. I didn't.

The last 100mg proved harder than the first 1,100mg reduction. I hadn't expected that.

I came out the other side with better pain control than I had on the strongest medications medicine could prescribe. I eliminated the central sleep apnoea and the 60% nightly death risk with it. I lost 8 stone in 9 months. I had not been properly conscious for years and suddenly I was.

I don't take any oral medication now. I never will again.

Complex Regional Pain Syndrome is clinically ranked as the most painful condition known to medicine. I developed it after two severe leg infections. I coped with it because by that point I was already accustomed to constant severe pain from bone and soft tissue breakdown. The CRPS pain was familiar territory. I didn't realise I had broken my shoulder in 2018 for six weeks. The pain was no worse than usual.

The GI Reality

Since August 2020, my gut has been on a liquid-only protocol. My gastrointestinal tract cannot absorb medication or nutrients reliably. I survive on alternating brief nutrition windows with 48 to 72 hour fasts.

Because I cannot absorb standard supplements, I've designed my own delivery system using high-dose raw ingredients. Daily: approximately 60g raw turmeric root with black pepper. The piperine in the pepper increases curcumin absorption by up to 2,000%, which is the only reason the anti-inflammatory effect reaches therapeutic levels in a gut like mine. Approximately 50g raw ginger as a pro-motility agent to fight Gastroparesis and Chronic Intestinal Pseudo-Obstruction. 300ml beetroot juice for blood pressure and cardiovascular function. These are not supplements. They are primary interventions.

The conventional medical pathway for someone in my situation is tube feeding, Total Parenteral Nutrition, or ileostomy. I have avoided all of it for six years, against a specialist prediction of failure within 18 months. Not through luck. Through active, systematic management of every variable I can control.

There is no validated clinical protocol for Classical Ehlers-Danlos Syndrome-related GI failure at this severity. I have built my own.

Not Compensation.
Substitution.

My blood pressure doesn't regulate. It operates in what I call a Square Wave, snapping from stroke-level hypertensive crisis at 203/141 mmHg to shock-level hypotensive collapse at 60/40 mmHg and back again in seconds. My connective tissue is so unstable that my joints have subluxed or dislocated over three million times. My gut is partially paralysed. I cannot absorb oral medication reliably.

In this space I stopped being a patient and started being a systems analyst.

What I've built is what I called Prosthetic Physiology. The formal definition: a system in which conscious, behavioural, mechanical, temporal, nutritional, environmental, and data-driven strategies actively replace failed biological reflexes.

01
Cognitive Prosthesis

I maintain continuous situational awareness of my physiological state. I do not rely on symptoms as warning signals because my physiology does not reliably signal distress in real time. I anticipate instability before it occurs. Decision-making replaces autonomic reflexes.

02
Mechanical Prosthesis

I use continuous movement as a circulatory support system. Without the muscle pump of my legs moving, blood pools in my lower extremities and my pressure begins its violent oscillation. Stillness is not rest for me. It's a haemodynamic gamble. I ride to stay pressurised.

03
Temporal Prosthesis

Effort, rest, nutrition, heat exposure, and recovery are all managed within defined physiological windows, scheduled in advance. I do not wait for symptoms to dictate action. Prevention is the only viable strategy.

04
Nutritional Prosthesis

I treat fuel intake as a controlled infusion, not a meal. My safe glucose corridor is 4.8 to 5.8 mmol/L. A reading of 5.9 is my smoke detector: the precise metabolic threshold where my system triggers a panic adrenaline surge. When that number appears, I deploy heat therapy and micro-doses of Vitargo immediately.

05
Environmental Prosthesis

Heat, cold, posture, and compression are active regulatory tools. A 45-minute steam or sauna protocol drives HRV rebound from below 20ms to above 60ms. The environment is not something I endure. It is part of how I regulate.

06
Data Prosthesis

Because my warning symptoms are absent or unreliable, I rely entirely on objective physiological data. Every 10 miles during a ride I receive data summaries via bone conduction headphones. Heart rate, power, pace, cross-referenced against my 80% output ceiling. I do not trust how I feel. I trust what the numbers say.

The 80% Rule

In elite cycling, pacing is about saving something for the sprint. For me, it's the difference between a successful ride and a multi-systemic collapse.

I never allow myself to exceed 80% of perceived maximum capacity. For a healthy athlete the remaining 20% is where gains happen. For me, that 20% is where my autonomic nervous system loses its ability to buffer stress, triggering inflammatory cascades and autonomic shocks that can take weeks to resolve. I am not chasing a personal best. I am maintaining systemic continuity.

I also operate by what I call the Lag Factor: I never plan based on how I feel today. I plan based on yesterday's data, because the delayed impact of exertion in my body is as certain as the exertion itself.

What Cycling Did

In December 2022 I was ending my 19th year as a full-time wheelchair user. Three months earlier I'd been up Snowdon in that wheelchair for Pulling Together Up Snowdon. On June 16, 2023, I rode the BHF London to Brighton, 54 miles in 4 hours 45 minutes on an old self-adapted hybrid bike. Three months after that I rode 197 miles over 4.5 days from Great Yarmouth to London for Race the Ship. I clocked 1,800 miles that year. I'd begun 2023 having to rebuild my leg muscles, learning how to adapt my bike so I could ride with my physical constraints.

In under two years at age 58, my VO2 max went from 30 to 55. My resting blood pressure came down from 198/141 to 108/61.

For someone with coronary heart disease, structural baroreflex failure, and square wave haemodynamics, those figures have no straightforward medical explanation. I'm not going to offer one beyond the system I've described above.

The riding is not separate from the medical management. It is the medical management.

Every day I live is a middle finger to the medical system that failed me for decades.

I ride because it is the only time I feel free. Pain is my operating environment, not my enemy.

In 2026, through persistence and consistency, I've started working as a freelance Accessibility and UX Consultant. It's a natural convergence: two decades of enterprise IT, combined with four and a half decades of lived disability and daily use of accessible technology. That combination gives me a perspective most IT professionals simply don't have, because they've never needed to.

Wheels for Tenacious continues to grow. The fifth ride is planned for September 2026: the UK's first ultra-endurance inclusive ride, where all riders regardless of experience, wheels, or circumstances complete 221 miles together as equals, coast-to-coast from Liverpool to Cardiff Bay.

Through my work with Wheels for Tenacious I've also volunteered as a ride leader for Try Cycling, a new initiative launched by Nene Park. Over the coming weeks and months I'll be completing first aid training, bicycle maintenance, and ride leader qualifications. The same person who spent 19 years in a wheelchair will be leading others onto bikes for the first time.

In May 2026 I'm riding London~Wales~London, 407km targeting 20 hours. Three weeks later, the Yorkshire Divide: 450 miles, 30,000 feet of climbing, 138-hour limit. In 2025 it had no finishers with a chronic illness.

I intend to be the first.
