Why will you not prescribe antibiotics?
Because most infections are viral, and antibiotics do nothing for viral illness — while causing thrush, diarrhoea, resistance, and the risk of masking what is actually happening.
What you get instead is more useful: what this is, how long it should last, and the specific signs that mean you need to be seen.
We earn nothing from prescribing, which is worth asking any service.
How do I know if it is sepsis?
Learn these, because delay is what kills. Slurred speech or confusion. Extreme shivering or muscle pain. Passing no urine all day. Severe breathlessness. A feeling that you are going to die. Skin mottled, blue or very pale.
Call 999 and say the word "sepsis". It changes how quickly you are assessed, and it is not an overreaction.
My child has a fever. When do I worry?
How they look matters more than the number on the thermometer. A child with 39°C who is playing is less concerning than one at 38°C who is floppy and uninterested.
Urgent: a rash that does not fade under a glass, difficulty breathing, floppiness or drowsiness, no wet nappies, a weak or high-pitched cry. Any baby under three months with a fever needs in-person assessment straight away.
Parental instinct is a legitimate clinical signal and one of the better predictors of serious illness in children.
How long should this last?
Longer than most people expect. A cold can take three weeks, a cough three weeks, sinusitis two to three.
What matters is the direction of travel. Gradually improving is reassuring; worsening after initially improving is not, and that pattern warrants review.
I have had a cough for a month.
Beyond three weeks it needs assessing rather than waiting out — more urgently with weight loss, coughing blood, hoarseness, chest pain, or a smoking history.
That is a chest X-ray conversation, and delay is what costs people.
I think I have shingles.
Be seen today if you can. The evidence-based treatment window is 72 hours from the rash appearing, and how quickly you were seen is often the main determinant of whether you get lasting nerve pain.
Urgent in person: shingles affecting the eye, eyelid or the tip of the nose — that is same-day ophthalmology, because sight is at risk.
I got a fever after coming back from abroad.
Seek urgent care today and say where you have been. Fever after travel to a malarial area is a medical emergency.
Malaria can develop up to a year after returning, is frequently mistaken for flu, and having taken your tablets correctly does not exclude it.
I have been exhausted since a virus weeks ago.
Post-viral fatigue is real and common, and it usually improves over weeks to a few months.
What is worth doing is excluding the things that look identical — iron deficiency, thyroid disease, B12 deficiency, glandular fever, coeliac disease and depression. Fatigue beyond a few months warrants proper assessment rather than being attributed to "post-viral" indefinitely.
Should I go back to work?
For diarrhoea and vomiting: 48 hours clear of symptoms. That one matters and is frequently broken.
Chickenpox: until lesions crust. Conjunctivitis: no exclusion at all, which surprises people. Otherwise, when you feel well enough — and we can issue a sick note from day one, which the NHS cannot.
I keep getting infections. Is something wrong?
Usually not, but it is worth a proper look. Recurrent infections can point to diabetes, iron deficiency, poorly controlled asthma, or occasionally an immune problem — and in children, frequent minor infections are often just nursery.
