Chronic red legs need heat, laterality and elevation checks before antibiotics; aspiration-related nodules and haemorrhage control add higher-acuity lessons.
Two chronically red legs rarely mean bilateral cellulitis.
Two red legs with chronic swelling and normal skin temperature deserve a venous assessment before another antibiotic course. Open the GPnotebook red legs discussion first because it changes the next consultation: check laterality, heat, duration, oedema, pulses and the response to elevation, then treat likely venous eczema with inflammation control and appropriate compression rather than chasing every ulcer swab.
Keep the same discipline when the finding looks obvious. Waxing and waning pulmonary nodules with cough, hoarseness, regurgitation or recurrent respiratory infections need foregut history and reflux testing before a malignancy-only line of thought. In acute care, intracerebral haemorrhage pressure lowering should avoid overshoot, while traumatic haemorrhagic shock needs early movement towards definitive haemorrhage control.
Start here when bilateral red legs are being called cellulitis. Put a hand on the skin, check laterality and duration, look for oedema and varicosities, and use elevation response before antibiotics or repeated wound swabs drive the plan.
Acute intracerebral haemorrhage needs careful pressure lowering, not a fast overshoot. The trauma and airway papers add a governance message: record whether bleeding control, tranexamic acid, first-pass success and complications are happening in real resuscitations.
Pulmonary nodules that wax and wane alongside cough, hoarseness, regurgitation or recurrent respiratory infections can be aspiration-related. The foregut lesson is to pair chest imaging with reflux history, objective testing, manometry and urgent action when para-oesophageal hernia becomes gastric volvulus.
Recurrent respiratory infections with chronic diarrhoea or failure to thrive should prompt immunoglobulin thinking, not another isolated infection plan. The main distinctions are IgA deficiency, common variable immunodeficiency, X-linked agammaglobulinaemia and hyper-IgM syndrome.
Psoriatic arthritis plus obesity is not only a weight conversation. The trial review separates ACR20 and ACR50 joint response from a composite endpoint driven partly by weight loss, and reminds clinicians to counsel gastrointestinal adverse effects before adding tirzepatide.
EBV serology can support neuroinflammatory reasoning, but the association with multiple sclerosis is not a complete causal story. Keep antibody results beside the clinical history, examination and established work-up rather than turning exposure into diagnosis.
Cardiology history is mainly for physiology-minded learners. It still helps when chest pain, valve disease or hypertrophic cardiomyopathy feels mechanical: heart rate, wall tension, contractility and dynamic gradients explain why bedside anomalies deserve careful checking.
When a request asks for antibiotics for red legs, ask for laterality, heat, duration, systemic features, photographs and current wound care. At examination, feel the skin, check pulses and elevate the leg if safe. Use swabs only when infection features change.
How can venous eczema be separated from cellulitis at the bedside?
Look at laterality, duration, warmth, oedema and response to elevation. Bilateral chronic redness with normal skin temperature and normal inflammatory markers makes active cellulitis less likely.
When should compression be checked further in red legs?
Higher-grade compression needs ABPI first. Class 1 compression can often start when pedal pulses are present and there are no major vascular risk factors or claudication.
What blood pressure pitfall matters in spontaneous intracerebral haemorrhage?
Precise reduction matters more than a fast fall. Watch for systolic blood pressure below 120 mmHg or a first-hour drop greater than 60 mmHg while lowering towards 140 mmHg.
