Spinal Cord Injury Secondary Complications: A Guide

Spinal Cord Injury Secondary Complications: A Family Caregiver’s Guide

After a spinal cord injury, the most common later health problems are pressure sores, urinary tract infections, breathing problems and pneumonia, blood clots, and autonomic dysreflexia. These problems develop over time because of the injury. They do not come from the accident itself.

Maybe you’re reading this at 2 a.m. with a notebook full of medicine names you can’t say. This guide is for you. Maybe your husband was hurt in a truck crash three weeks ago. Maybe your daughter was attacked in a parking garage. Now she’s in a rehab unit. You didn’t ask to become a nurse, a scheduler, and a records clerk overnight. But here you are.

This guide is written for you, the family caregiver. It’s not for a doctor or a general reader. It explains the long-term health risks in plain words. That way you know what to watch for between appointments. This is educational information, not medical advice. Your loved one’s care team should always guide care decisions.

We handle catastrophic spinal cord injury cases. We’ve sat with families who learned about these problems the hard way. Learning about them early helps you protect your loved one. Later, it helps you see why the true cost of care is so much bigger than the first hospital bill.

Why secondary complications happen after a spinal cord injury

These problems happen because a spinal cord injury changes how the body controls itself. It leaves lasting weak spots. The first injury is only the start of the story.

The spinal cord carries signals between the brain and the body. When it’s damaged, those signals stop or get scrambled. This affects much more than movement. It can change how the bladder, bowels, blood pressure, skin, and lungs work. These systems used to run on their own.

The type and severity of problems often depend on the level and completeness of the injury. Doctors measure completeness with the ASIA Impairment Scale. It comes from the American Spinal Injury Association. It’s the “A through E” grade you may see on your loved one’s chart. Injuries higher up in the neck (called cervical injuries) tend to cause more serious problems than lower ones. To see where your loved one’s injury falls, read our guide on spinal cord injury levels explained.

Here’s the part worth holding onto. Many of these problems can be prevented or managed with careful, steady care. Knowing the warning signs is one of the most powerful things you can do.

Pressure sores: common, silent, and largely preventable

Pressure sores (also called pressure injuries) are one of the most common problems after a spinal cord injury. They are also one of the most preventable. They form when steady pressure cuts off blood flow to the skin.

When someone can’t feel or move part of their body, they can’t shift their weight. They also can’t feel the ache that normally says “move.” So the skin breaks down quietly. The Mayo Clinic lists pressure injuries as a common problem after spinal cord injury.

Watch these common spots: the tailbone, hips, heels, elbows, shoulder blades, and the back of the head. Early warning signs include:

• Red, purple, or discolored skin that doesn’t fade when pressed
• Skin that feels warmer or cooler than the skin next to it
• An open sore or blister
• Swelling or firmness under the skin

You can help. Reposition your loved one on the schedule the care team sets. This is often every two hours in bed. Check the skin every single day. Use the pressure-relief cushions and mattresses the doctors prescribe. If a sore isn’t treated, it can grow deep and turn into a dangerous infection. Never wait one out. Call the care team early.

Urinary tract infections and bladder complications

Urinary tract infections (UTIs) are very common after a spinal cord injury. That’s because the injury often disrupts bladder control. Many survivors use a catheter, which raises the risk of infection.

The Mayo Clinic explains that a spinal cord injury can affect bladder control. This raises the risk of UTIs and kidney problems. Here’s what surprises many families. Your loved one may not feel the usual burning pain. So you have to watch for other clues.

Warning signs of a UTI include:

• Fever or chills
• Cloudy, dark, or bad-smelling urine
• More muscle spasms (spasticity) than usual
• Feeling generally unwell, tired, or confused

Take these signs seriously. A UTI can get worse fast and spread. Over time, repeated infections can harm the kidneys. Getting quick medical care matters every single time.

Respiratory complications and pneumonia

Breathing problems are a leading serious risk. This is especially true with higher neck injuries, which weaken the muscles used to breathe and cough. Pneumonia is one of the biggest early dangers.

When those muscles are weak, mucus builds up in the lungs. That mucus becomes a home for infection. The Mayo Clinic lists breathing problems as a complication tied to spinal cord injury.

Watch for:

• Shortness of breath or fast breathing
• Chest congestion or a wet-sounding cough
• Fever
• Unusual tiredness or confusion

Some survivors with high neck injuries need long-term breathing support, such as a ventilator (a machine that helps them breathe). That support is one reason lifelong care costs so much. Report any breathing change to the care team right away.

Autonomic dysreflexia: the emergency every caregiver must recognize

Autonomic dysreflexia is a sudden, dangerous spike in blood pressure. It is a medical emergency. It’s most common in injuries at or above roughly the mid-back (T6 and above).

The Mayo Clinic describes it as a rise in blood pressure that can be life-threatening. It can happen after a spinal cord injury. It occurs when the body overreacts to something below the level of injury. Often the person can’t feel that thing.

Common triggers include a full bladder, a blocked or kinked catheter, constipation, or skin irritation. Warning signs come on fast:

• A pounding, severe headache
• Sweating and flushing above the level of injury
• A blotchy, flushed face
• A sudden, very high blood pressure reading

Do not wait this out. If it happens, sit the person upright. Loosen tight clothing. Look for an obvious trigger. Then get medical help right away. Ask the care team in advance to write out an emergency plan. Keep it on the fridge. The Christopher & Dana Reeve Foundation is a good resource for caregiver education on this.

Autonomic dysreflexia is not the same as spinal shock, which happens right after the injury. To learn the difference, read our guide on what is spinal shock.

Blood clots and cardiovascular complications

Blood clots are a serious risk after a spinal cord injury. That’s because less movement lets blood pool in the legs. This can cause a deep vein thrombosis (DVT), which is a clot deep in a limb.

The Mayo Clinic notes that changes in blood flow after a spinal cord injury raise the risk of clots. These include DVT and pulmonary embolism. A pulmonary embolism happens when a clot travels to the lungs. It is life-threatening.

Watch for warning signs of a clot in an arm or leg:

• Swelling in one limb
• Warmth or redness
• Skin that looks off-color

The injury can also change how the body controls blood pressure over the long term. That’s why the care team watches circulation closely. They often use prevention steps like compression and blood-thinning medicine. Call for help fast if you see clot signs. Act even faster if they come with sudden shortness of breath or chest pain.

Other complications families should know about

Several other long-term problems are worth knowing. Each one shapes daily life and long-term care.

Bowel problems. Loss of bowel control is common. Survivors usually follow a set bowel program. Problems here can also trigger autonomic dysreflexia.

Spasticity and chronic pain. Many survivors live with muscle tightness and spasms (called spasticity). Nerve pain (called neuropathic pain) is also common and can be constant. Both need ongoing care.

Bone density loss. After paralysis, bones can weaken. This raises the risk of breaks. Sometimes a break comes from a minor bump during a transfer.

Mental health — including yours. Depression and anxiety are common for survivors. They are also common for caregivers, and that part rarely shows up in clinical handouts. Maybe you feel exhausted. Maybe you feel resentful one minute and guilty the next. Maybe you’re grieving a life that changed overnight. None of that makes you a bad caregiver. It makes you human. Your own care is not optional. Asking for help is a strength. A social worker on the rehab team can connect you with caregiver support.

How families can lower the risk day to day

Families lower the risk of problems most by following the care team’s plan closely. Catch warning signs early. Being consistent is what protects your loved one.

Practical steps that help:

• Check the skin fully, every day
• Reposition on the schedule the care team sets
• Follow bladder and bowel routines exactly
• Track symptoms, temperatures, and any changes in a notebook or phone app
• Keep every appointment and write your questions down before you go

Here’s one more habit that pays off: keep records. Save discharge papers, medicine lists, imaging reports, and dated notes about each problem and how it was treated. This helps the care team spot patterns early. And if someone else’s carelessness caused the injury, those same records become the backbone of any future claim. Details fade from memory in months. A note written at the time does not.

Why lifelong complications matter to a catastrophic injury claim

These problems matter to a claim because they drive decades of medical costs. That means ongoing care, equipment, home health, and repeat hospital stays. A fair claim must account for the future, not just the bills already in the mail.

In the catastrophic spinal cord injury cases our attorneys handle, we see how these costs pile up. A single serious pressure sore or bout of pneumonia can mean weeks back in the hospital. Ventilator support, catheter supplies, home changes, and skilled home care add up year after year. The Christopher & Dana Reeve Foundation publishes data on how many Americans live with paralysis. Long-term data is also tracked by the National Spinal Cord Injury Statistical Center (NSCISC). The point is simple: these are lifelong realities, not one-time events.

Someone else’s carelessness may have caused the injury. For example, a truck crash. Or a violent attack that an unsafe property failed to prevent, such as broken locks and gates, poor lighting, no cameras, or no security staff. In that case, a claim should account for those future medical needs. When a property owner fails to provide reasonable security and someone is hurt as a result, the law calls this negligent security. A claim may then be made against the owner. To document future needs, experts usually build a life-care plan. That’s a detailed plan of the care, equipment, and services a survivor will need over a lifetime. Medical and economic experts help build it. This is how a claim can show the true, lifelong cost of care — not just the emergency room visit.

Timing matters too. In Florida, most negligence claims that start on or after March 24, 2023 must be filed within two years. This rule comes from Fla. Stat. §95.11. Florida also follows a shared-fault rule (called comparative negligence) under Fla. Stat. §768.81. This can lower a recovery by the person’s own share of the fault. Deadlines and details vary by situation. So it’s worth asking a lawyer sooner rather than later.
