How to prepare for health appointments about post-viral symptoms

Post-viral conditions are difficult to explain quickly. The symptoms overlap, the timeline is long, the investigations are often normal, and the whole picture only makes sense when you step back and look at it together. That’s hard to do in a 10-minute GP slot or a 30-minute outpatient appointment with someone who has never met you before.

Over the past three years, I’ve had dozens of appointments across primary care, a specialist headache service, a post-COVID rehabilitation service, and NHS respiratory medicine. The single most useful thing I’ve done is learn how to present my situation clearly and concisely on paper, so that whoever I’m seeing can understand the full picture in under a minute.

Before every appointment, I prepare a single-page summary. One side of A4, no more. The aim is that the clinician can read it in 30 seconds and immediately have a working understanding of who you are, what’s happened, what’s been tried, and what you want to discuss.

Mine typically includes:

A brief summary of my presentation in two or three sentences: when the illness started, what the main symptoms are now, and how they affect my function.
A short table of current objective data: my average resting heart rate, heart rate variability, and symptom scores over the past month. Nothing elaborate. Just enough to show there’s something measurable going on and that you’re tracking it.
A list of current medications and supplements, with doses.
A list of key previous medications and whether they helped.
A list of investigations completed and their results, one line each.
Two or three specific questions I want to discuss.

That’s it. The questions at the end are important. Clinicians are used to patients arriving with a vague sense that something is wrong and hoping the doctor will work out what to do. Arriving with specific, clear questions signals that you’ve thought about your situation and have a concrete reason for being there. It also helps the clinician structure the appointment, which they’ll appreciate when time is short.

Why this matters more than you’d think

The biggest practical challenge I’ve faced is continuity of care. Post-viral conditions involve multiple specialties, long waiting lists, and frequent changes of clinician. In three years, I have rarely seen the same doctor twice. Every appointment risks becoming a fresh explanation of a complex history to someone who is encountering it for the first time, often over the phone, and who is very reasonably left a bit overwhelmed.

The one-pager solves this. It means you’re not relying on the clinician having read your notes (they often haven’t, or the notes don’t capture the full picture). It means you’re not spending the first seven minutes of a ten-minute appointment on backstory. And it means the clinician has something to refer to during and after the appointment, which can improve the quality of whatever gets written in your record.

I’ve found that appointments where I brought a one-pager were significantly more productive than those where I didn’t. The conversations were more focused, the clinician asked better questions, and I left with clearer next steps.

Presenting your symptoms

Lead with symptoms, not a diagnosis. Even if you’re fairly sure what’s going on, opening with “I think I have POTS” or “I think this is ME/CFS” can put a clinician on the back foot. Opening with a factual description of what’s actually happening to you (“my resting heart rate has risen from the low 60s to the low 80s since a viral illness, I get breathless getting dressed, and my symptoms worsen 6–8 hours after exertion”) gives the clinician something concrete to engage with.

If your symptoms are worse on standing and improve when you lie down, say this explicitly and early. The orthostatic pattern is the thing that points towards autonomic dysfunction, and it’s easy to miss if the conversation focuses on fatigue or breathlessness in general.

What to ask for

This depends on where you are in the process, but some broadly useful things:

If you haven’t had basic bloods done, ask for them. A full blood count, thyroid function, inflammatory markers (CRP, ESR), ferritin, B12, folate, vitamin D, renal function, liver function, and HbA1c will rule out common treatable causes of fatigue and are reasonable to request.

If you suspect an orthostatic heart rate problem, ask for a lying and standing heart rate check. This takes a few minutes in the room and is very informative if you have a significant orthostatic rise. Ask specifically for a 10-minute standing measurement if possible, as shorter tests can miss a gradual rise.

If initial investigations are normal but your symptoms are significantly affecting your life, ask for referral to a relevant specialist. Framing this as “my symptoms are significantly affecting my ability to work and I’d like a specialist opinion” is a reasonable request that’s hard to decline.

If you’re already under a specialist service, ask what the plan is, what happens next, and what you should do if things deteriorate before your next appointment. Clarity on the plan is worth more than additional tests.

Working with the system rather than against it

The NHS is under enormous pressure. Waiting lists are long. Appointments are short. Clinicians are often managing dozens of patients in a session. None of this is your fault, and none of it means your symptoms are less valid, but acknowledging the reality of it can help you work within the constraints rather than against them.

Being concise and prepared isn’t about performing for the doctor. It’s about making the most of limited time. A clinician who has to spend the whole appointment piecing together your history has no time left to think about what to do next. A clinician who understands your situation in the first two minutes has eight minutes to actually help.

If you feel your concerns aren’t being addressed, asking to be referred elsewhere or asking to see a different clinician within the same service is within your rights. A written follow-up message through your GP’s online system (Patient Access, the NHS App, or similar) creates a record of what you’ve asked for, which is more durable than a verbal conversation.

If NHS waiting times are very long and you have the means, a single private consultation with a relevant specialist can sometimes accelerate things. Not for ongoing treatment, but for a diagnosis letter or opinion that you can bring back to your NHS team. A letter from a cardiologist or neurologist saying “this patient has X and would benefit from Y” carries weight.

Useful organisations

PoTS UK is the main UK charity for postural tachycardia syndrome. Their website has good information on the condition, management, and a clinic finder listing NHS clinicians with an interest in PoTS. If you’re trying to work out who to ask your GP to refer you to, start here.

Action for ME provides information, support, and advocacy for people with ME/CFS across the UK. They offer free services including a telephone information line, an adults’ advocacy service, and family support. Useful if your presentation has significant fatigue and post-exertional malaise features.

National Migraine Centre is a charity-run specialist headache service. If you have post-viral head pain that your GP isn’t sure how to manage, they’re worth contacting. They offer free appointments (expect to wait a few weeks, and they’ll gently ask for a donation after your consultation) or you can pay to be seen more quickly. I’ve found them knowledgeable and practical.

Everything here is based on my own experience. NHS practice varies by region, and what works in one area may not work in another. This isn’t medical advice: it’s practical guidance from someone who has spent three years learning how to get the most out of a system that wasn’t designed for conditions like ours.
