The effects of a cold injury can continue long after an exercise or deployment has ended. For some veterans, symptoms such as pain, numbness, tingling and sensitivity to cold can continue long after the original exposure.
This is particularly relevant to Non-Freezing Cold Injury, often shortened to NFCI. It can develop when hands or feet are exposed to cold and wet conditions for a prolonged period without the tissue actually freezing.
Not everyone who experiences a cold injury will develop long-term problems. But where symptoms persist, they can affect everyday life well after someone has left the Armed Forces.
What is a non-freezing cold injury?
Non-freezing cold injury happens when tissue is cooled for a prolonged period without actually freezing. The Ministry of Defence describes NFCI as one of the most common types of cold injury seen in defence and notes that it often occurs during training exercises.
It is different from frostbite, frostbite is a freezing cold injury, where tissue freezes. NFCI develops above freezing point, often in cold and wet conditions, and commonly affects the hands or feet.
Because the original exposure may have happened years ago, some veterans only connect current symptoms with their service once those symptoms begin to interfere with work, sleep, exercise or normal day-to-day activities.
Why can symptoms continue for years?
Research involving UK Armed Forces personnel with chronic NFCI has found that the condition can involve injury to the sensory nerves. In one study, participants reported persistent numbness, altered sensation and chronic pain, and every participant experienced increased sensitivity to cold.
The same study found that, on average, people were assessed by a specialist several years after the original injury. This does not mean everyone with NFCI will have symptoms for that long. It does show that, for some people, the effects can remain significant years after the original cold exposure.
The Armed Forces Compensation Scheme also recognises that cold sensitivity can continue beyond the early recovery period. Its injury tariff includes NFCI where neuropathic pain and functional problems remain after 26 weeks, and notes that continuing cold sensitivity may still be present after that point.
What can long-term cold injury symptoms feel like?
Persistent symptoms can vary from person to person. They may include:
- pain or burning sensations in the hands or feet
- numbness, tingling or pins and needles
- unusual sensitivity to cold temperatures
- changes in temperature sensation
- discomfort when returning to cold or wet conditions
- difficulty with walking, standing, gripping or other everyday tasks in more severe cases
These symptoms are not unique to NFCI, so they should not be treated as proof of a diagnosis on their own. If symptoms are ongoing, a medical assessment can help establish what may be causing them.
Why does cold sensitivity matter so much?
For someone who has not experienced it, cold sensitivity can sound fairly minor. In practice, it can be difficult to manage. Normal winter weather, working outdoors, handling cold objects or simply being in an unheated environment may make symptoms worse.
That can have a knock-on effect on work, exercise, travel and everyday routines. Some people find that they have to change footwear, avoid certain environments or plan much more carefully around cold weather than they did before the injury.
This is one reason a service-related cold injury can remain relevant long after a person has left uniform, even when the original exposure happened during training many years earlier.
What about freezing cold injuries?
Freezing cold injury is different from NFCI because the tissue itself freezes. Frostbite is the best-known example. The long-term effects can also be serious, particularly where there has been deeper tissue damage.
This article focuses mainly on NFCI because that is where the strongest search demand and military research sit. However, veterans who experienced frostbite or another freezing cold injury during service may also have lasting symptoms and should not assume that an old injury is irrelevant simply because the exposure happened years ago.
What if the injury happened during military training?
Cold injury is not limited to overseas operations. MOD guidance specifically recognises that NFCI commonly occurs during UK training exercises, where prolonged cold and wet exposure can affect the hands and feet.
That means the circumstances around the injury matter. Useful details can include where the training took place, how long you were exposed to cold or wet conditions, what kit was available, whether you reported symptoms at the time, and whether you later received medical treatment.
If the event was a long time ago, you may not remember every detail. It is better to be accurate about what you do remember than to fill in gaps by guessing.
Can an old military cold injury still be worth investigating?
Potentially, yes. The fact that you have left the Armed Forces does not automatically make an old service-related cold injury irrelevant.
If you still experience pain, numbness, tingling or marked cold sensitivity and believe the problem may be linked to cold exposure during service, it may be worth checking what medical evidence exists and whether your circumstances fit a route that can still be considered.
A claim is not established simply because symptoms have lasted a long time. The service history, medical evidence, timing and the correct compensation or civil route all matter.
What information could be useful?
If you are looking back at an old cold injury, useful information can include:
- your dates of service and the unit or role you were in
- where and when the cold exposure happened
- whether the exposure happened during training, an exercise or an operation
- what symptoms you experienced at the time
- whether the injury was reported or recorded
- any GP, hospital, military medical or specialist records
- how the symptoms affect you now
You do not necessarily need every document before asking whether the matter is worth looking into. The first step is usually to establish a clear timeline and understand what evidence may be available.
What should veterans with persistent symptoms do next?
If cold injury symptoms are still affecting you, the first priority is your health. Speak to a healthcare professional if you have ongoing pain, altered sensation or other symptoms that have not been properly assessed.
If you believe those problems may be connected to your military service, you can then look at whether there is a relevant compensation or civil claim route. VFV focuses on military cold injury claims and can help veterans understand whether their circumstances may be worth investigating further.
Frequently asked questions
Can non-freezing cold injury symptoms last for years?
They can in some people. Research involving UK Armed Forces personnel with chronic NFCI has documented persistent numbness, altered sensation, cold hypersensitivity and neuropathic pain years after the original exposure. Not every cold injury becomes chronic, so individual assessment matters.
Is NFCI the same as frostbite?
No. NFCI develops without tissue freezing and is usually associated with prolonged cold and wet exposure. Frostbite is a freezing cold injury where the tissue itself freezes.
Can military training cause non-freezing cold injury?
Yes. MOD guidance specifically recognises NFCI as a common Defence cold injury and notes that many cases occur during training exercises.
Can I look into a cold injury claim after leaving the Armed Forces?
Potentially. Leaving service does not automatically prevent every route from being considered. The right route will depend on the circumstances of the injury, when it happened, the evidence available and any relevant time limits.
