Know the red flags and what to expect
Occasional burning feet that settles quickly after rest or cooling is not an emergency. But if the burning happens on most nights and continues for more than two weeks without improving, it is worth a medical check-up. The reason for the two-week marker is practical: the most common causes — diabetic neuropathy, B12 deficiency, and alcohol-related neuropathy — are all easiest to treat early, and all are diagnosed with simple blood tests.
Peripheral neuropathy is present in roughly 10% of people over 40 and 20–30% of people over 70, and diabetes accounts for about a third to a half of cases. When neuropathy is caught early, the underlying driver can often be slowed or reversed: blood sugar control, B12 replacement, and stopping alcohol all improve symptoms. Left alone, burning can progress to numbness, and numb feet hide injuries that then become infected — a leading reason for serious foot complications in people with diabetes.
Start with your GP, who can run the initial blood tests and examine the feet. Depending on the findings you may be referred to a neurologist (nerve damage), an endocrinologist (diabetes), or a vascular surgeon (poor circulation). A podiatrist is a useful addition for ongoing foot care, especially if you have diabetes.
If you are waiting for an appointment, the relief strategies page has safe, non-medical ways to make nights more comfortable in the meantime.
Answering these in advance makes the appointment faster and more focused — and the answers alone often point to the diagnosis before blood tests are back.
Waiting a few weeks with occasional burning is low-risk. Waiting months with nightly burning is how treatable causes become harder to reverse and how neuropathy progresses from burning to numbness. While you wait for an appointment, keep a simple diary (which nights, how intense, what helped), continue the relief measures, and if you have diabetes, check your feet daily for cracks or sores. If the burning spreads rapidly, or you develop weakness or a non-healing sore, move the appointment up rather than waiting.
A few minutes of preparation makes the consultation far more productive. Write down when the burning started, how often it happens, whether it has spread, and anything that makes it better or worse. Bring a list of all medications — including over-the-counter tablets and supplements — and be ready to answer honestly about alcohol intake, because alcohol-related neuropathy is one of the most common and most reversible causes. If you have diabetes, bring your recent blood sugar readings if you have them. This information, combined with the examination and blood tests, usually identifies the cause in a single visit.
The blood panel covers the treatable causes in one draw: HbA1c or fasting glucose flags diabetes and prediabetes; vitamin B12, iron studies, and thyroid function cover the deficiency causes; and kidney function checks for the uraemic toxins of chronic kidney disease. If those are normal and the burning persists, nerve conduction studies measure how fast signals travel down the leg nerves — they confirm whether neuropathy is present and how severe it is. The ankle-brachial index, a two-minute blood-pressure comparison, screens for peripheral artery disease. The vast majority of people get a clear answer from the first two steps alone.
