The calf that felt tight yesterday is hot this morning, and the sock has left a dent that has not filled. He is still going to work on it because last time someone said it was a sprain. By the time they search swollen leg cellulitis they already know it is not a sprain. The real question is whether this is skin, a clot, or both, and whether waiting until Monday is still a choice.
A hot, painful, swollen leg is 2 diagnoses until someone has looked. Antibiotics for infection and a same day clot pathway are not either or. Waiting for it to go down over the weekend is the dangerous option.
Chest pain, signs of a stroke, severe breathlessness, heavy bleeding, a severe allergic reaction or symptoms of sepsis need 999 or A&E immediately. A clinic appointment is the wrong door for those.
Is a swollen leg cellulitis, a clot, or both?
The short version is this. Infection in the skin and a clot in the vein can look alike, and they can sit together. Treating one does not prove the other is absent. I would rather send you along 2 pathways in the same afternoon than pick the prettier story and be wrong.
People delay because the leg still takes a shoe, or because there is a bite, or because they have had this redness before and tablets sorted it. The pattern matters more than the single reading of “it happened after a walk”. Sudden swelling in one calf, heat, and pain that is out of proportion to a bruise is not a wait and see.
If the person is breathless, faint, or the swelling is going up while they talk, that is 999. Get it examined today. Clinique Alpa if you can be seen. A&E if you cannot.
What does the GP actually examine?
What I look at in clinic is time and laterality first. 1 leg or 2. Hours or days. Whether it followed a flight, an operation, a plaster, a period of sitting, or a break in the skin. Whether they have had a clot before. Whether they are pregnant, or recently were. Whether cancer treatment is in the background. Those facts change the next hour, not the next week.
Then I look. Demarcation of redness. Tracking up the leg. Breaks in the skin between the toes, because that is often the door the bacteria used. Heat compared with the other side. Calf circumference, same point on both legs, written down. Pulses. The groin. The abdomen if there is any suggestion this is more than a calf. The chest, because a clot that has already moved is a lung problem, not a skin one.
I ask about breathlessness, chest pain, coughing blood, and feeling faint, even if they came in only about the ankle. The piece most people miss is that a quiet chest does not finish the job. A person can have a clot in the calf and look well. A person can have spreading infection and a normal temperature. We examine anyway.
2 legs that puff by evening, with pitting to the knee and a bit of breathlessness on the stairs, is often heart or vein pressure rather than infection. A hot, red, extremely tender first toe is often gout. A sudden calf pop while stretching, then bruising lower down a day later, can be a ruptured cyst behind the knee. Naming those is useful. Using them to talk someone out of a proper look is not.
If the picture is bacterial, antibiotics are ordinary and they start after the assessment, not because the patient asked firmly. If the picture has clot features, I do not sit on it until a Monday ultrasound. I route them the same day into the pathway that can rule a clot in or out. If both are plausible, we do both. That is not indecision. That is how this actually behaves in clinic.
Dr Morawala looks, from the surgical side, if there is a collection that may need draining. Most of these legs do not. The ones that do should not wait in a GP room while we admire them. I will say so.
I cannot promise the redness will fade on a timetable, or that a scan will be normal, or that you will avoid hospital. You get an examination and a plan. You do not get a guaranteed outcome.
When should I come in sooner?
Some of this should not come to Palmers Green at all. It should go past us, to 999 or A&E, now.
- Breathlessness, chest pain, coughing blood, or feeling faint.
- The person is confused, very feverish, shivering, or the redness is spreading over hours.
- The whole leg is white, mottled, or the pulses in the foot are gone.
- Sudden swelling after a long journey, surgery, or a previous clot, especially if the calf is tight and tender.
- They cannot weight bear, or the pain is escalating despite what they have already taken.
- They are pregnant, recently pregnant, or have active cancer, and one leg has gone.
When this comes up in consultation I would rather you were in A&E with a false alarm than at home with a clot in the lung. Come in sooner if the redness is new today and you can still travel. Call 999 if you cannot.
How do we see this at Clinique Alpa?
This is a same day problem, subject to the diary, not a problem for next week. A 30 minute appointment in clinic is £100. If you cannot get here, a home visit is £250 in the day and £450 at night, each up to an hour. Suitability is assessed first. A home visit is not an emergency service. If we cannot reach you in time, A&E is the honest answer.
Read the same day private GP page and take a live slot if there is one. If leaving the house is unwise but this is not 999, read the home visiting GP page and tell us the postcode. Fees sit in full on the appointments and fees page. A referral letter is £50 where it is clinically appropriate after we have actually examined you.
Bring a list of what you take, any previous clot letters, and a clear view of the other leg. Do not wait for it to go down over the weekend. If we cannot see you today, go to A&E rather than holding the diary until Tuesday.
Get a hot, painful, swollen leg examined today. Read our fees page, or call 020 8882 8088. Home visits £250 day, £450 night, published in full. In an emergency call 999. Subject to availability.
