The typical presentation of heart failure in primary care is insidious, with progressive breathlessness on exertion, ankle swelling, orthopnoea or paroxysmal nocturnal dyspnoea. Not all patients will have all these symptoms, and in many patients there may be other causes. If a GP suspects heart failure, then the key blood test is B-type natriuretic peptide (BNP). ⋯ ACE inhibitors (or angiotensin receptor blockers) and beta-blockers licensed for heart failure (carvedilol, bisoprolol, nebivolol) remain the mainstay of treatment in addition to as small a dose of diuretic as possible to control any fluid retention. Aldosterone antagonism is recommended by the 2012 ESC guidance for all patients who remain symptomatic despite an ACE inhibitor and beta-blocker. If the rhythm is sinus but the heart rate is 75 beats per minute, therapy needs to be optimised, perhaps by increasing the beta-blocker dose, if possible, or by the addition of ivabradine.

Around 1-2 people per thousand present with an acute episode of pain caused by renal stones each year. Renal colic is classically sudden in onset, unilateral, and radiates from loin to groin. Renal pelvic or upper ureteric stones usually cause more flank pain and tenderness while lower ureteric stones cause pain radiating towards the ipsilateral testicle or labia. ⋯ All patients who are managed at home should have renal tract imaging within a week by fast track referral to radiology or as an urgent urology outpatient referral as per local guidelines to rule out an obstructed urinary system. Patients with recurrent stones should be advised to maintain a copious fluid intake (>2 L/day) to reduce the concentration of the urine. A reduction in salt intake (ideally <2g/day) and animal protein in the diet can help to reduce stone formation.

Complex regional pain syndrome (CRPS) is divided into two types. Type I occurs without obvious nerve injury. In type II, a peripheral nerve injury is present, although pain may not be limited to the distribution of that nerve. ⋯ Aggressive treatment in the early stages improves prognosis. Many cases, especially those with relatively minor symptoms, will resolve spontaneously. Patients who are symptomatically deteriorating, despite regular analgesia, neuropathic agents and physiotherapy, should be referred to a specialist.

Neuropathic pain is defined as 'pain arising as a direct consequence of a lesion or disease of the somatosensory system'. It may reflect a widespread neuropathic process (e.g. diabetic neuropathy) or a more focal disorder (e.g. post-herpetic neuralgia). The practical importance of recognising neuropathic pain (as distinct from nociceptive pain) lies in the difference in effective treatments. ⋯ A specialist opinion should be sought where the diagnosis is uncertain, or the patient's condition is rapidly deteriorating or uncontrolled. This may be a specialist in a particular condition, to address issues of primary diagnosis, or a specialist in pain medicine to advise on, or provide, further treatment. Patients who are struggling with their pain are best served by specialist centres that can endeavour to explain the condition and encourage self-management.
