15 Symptoms People With Peripheral Neuropathy Can Experience

2. Numbness

Numbness is one of the most common symptoms of peripheral neuropathy. You may notice it first in your toes or the bottom of your feet, and it can spread to your hands or legs over time. When you have numbness, you lose the ability to feel touch, pain, or temperature clearly.

Your feet may feel “asleep” or thick, as if you are wearing socks when you are not. Simple sensations, like the floor under your feet, can seem dull or distant. Because you cannot feel pain well, small injuries may go unnoticed. A pebble in your shoe or a minor burn from hot water can cause damage before you realize it. This is why foot problems are common when neuropathy affects your feet.

Numbness can also affect balance. When your nerves cannot send clear signals about position and movement, you may feel unsteady. You might trip more often or feel unsure when walking in the dark.

3. Pain

Pain is one of the most common symptoms you can experience with peripheral neuropathy. Damaged nerves send wrong signals to your brain, so you may feel pain even when nothing is causing harm. The pain often starts in your feet and legs, then moves to your hands and arms. Many people describe it as burning, stabbing, sharp, or electric-like. It can also feel like deep aching or throbbing.

You may notice that pain gets worse at night. Even light touch, such as bedsheets on your skin, can hurt because your nerves misread normal contact as pain. Some days feel manageable, while others limit your movement or sleep. Poor sleep can make the pain feel stronger the next day.

Doctors may treat nerve pain with certain types of antidepressants, antiseizure medications, or topical treatments. These drugs do not cure nerve damage, but they can help calm the pain signals your nerves send.

4. Weakness

Peripheral neuropathy can damage the nerves that control your muscles. When this happens, you may notice weakness in your hands, feet, arms, or legs, which makes simple tasks feel harder than usual. You might struggle to grip objects, turn a key, or button a shirt.

In your legs, weakness can make it harder to climb stairs or stand up from a chair. Some people notice their foot slaps the ground when they walk, or they have trouble lifting the front part of the foot, which can raise your risk of tripping.

Muscle weakness may affect one area or several parts of your body. It often starts slowly and worsens over time. You may also see muscle thinning, which happens when weak muscles shrink from lack of use. If weakness affects the muscles that control posture, you may feel unsteady. You might need to hold onto walls or furniture for support.

5. Changes in the Way You Walk

Peripheral neuropathy can change how you walk. When nerves in your feet and legs do not send clear signals, you may struggle to feel the ground under you, which makes your steps slower and less steady. You might notice that you shuffle your feet instead of lifting them.

Some people develop foot drop, which can cause the toes to drag on the floor and increase the risk of tripping. Balance problems are also common. When you cannot fully sense pain, touch, or temperature in your feet, your brain gets less information about your position.

This loss of awareness can make you sway or feel unsteady, especially in the dark. Weak leg muscles may cause you to lean on walls or furniture for support. You may feel safer using a cane or holding onto someone’s arm.

6. Loss of Balance

You may notice that you feel unsteady when you stand or walk. Peripheral neuropathy can damage the sensory nerves that help you sense the position of your feet. When these nerves do not work well, your brain gets less information about where your body is in space.

You might sway while standing still. Walking on uneven ground can feel harder than it used to. Some people say they feel like they are walking on soft foam or thick socks, even when barefoot.

Loss of balance often links to numbness in the feet. If you cannot fully feel the floor, you may struggle to adjust your steps. This can raise your risk of trips and falls, especially in dim light.

You may also notice trouble with coordination. Simple tasks like turning quickly, climbing stairs, or stepping off a curb can feel unsafe. You might need to hold onto walls or railings more often.

7. Swollen Feet

You may notice that your feet look puffy or feel tight in your shoes. Swelling can happen when fluid builds up in the tissues. Peripheral neuropathy often starts in the feet, so changes like this are common. Nerve damage can affect how well your body controls blood flow and fluid balance. When nerves do not send clear signals, blood vessels may not tighten or relax the right way, which leads to fluid pooling in your lower legs and feet.

Swollen feet may feel heavy or stiff. Your skin might look shiny, and you may see indentations after pressing on it or after wearing socks. Some people also notice numbness or tingling along with the swelling.

If you have diabetes, your risk may be higher. High blood sugar can damage nerves and blood vessels over time, which makes it harder for your body to manage circulation in your feet.

Swelling can also increase your risk of skin problems. When your feet are swollen and numb, you may not feel small cuts or pressure spots. These minor injuries can worsen if you do not notice them.

8. Loss of Muscle Tone in Hands and Feet

You may notice that your hands or feet look thinner than before. Muscles can lose their normal shape and firmness when nerve damage affects the motor nerves that control movement. This loss of muscle tone often happens slowly because when nerves cannot send clear signals, your muscles do not work as much as they should and shrink over time.

You might see this in your hands, where the space between your fingers looks hollow, or in your feet and lower legs. Loss of muscle tone can make daily tasks harder. You may struggle to grip objects, button a shirt, or open jars. In your feet, weak muscles can change how you walk and raise your risk of tripping.

9. Sensitivity to Touch

You may notice that even light contact feels unpleasant or painful. A soft shirt, bedsheets, or a gentle hug can trigger discomfort. Damaged sensory nerves send the wrong signals to your brain, causing normal touch to feel like pain, which is called allodynia.

You might also feel sharp, burning, or electric-like sensations from simple contact. This symptom often affects your feet and hands first. For some people, it becomes worse at night and disrupts sleep. You may find yourself avoiding certain fabrics or activities because they cause discomfort.

Sensitivity to touch can also come with other sensory changes such as tingling, numbness, or reduced ability to sense temperature. At the same time, your skin may seem overly reactive to the smallest contact. Peripheral nerves lose their ability to send clear messages and instead send pain signals, which makes everyday touch feel far more intense than it should.

10. Heat Intolerance

Heat intolerance makes you feel overheated faster than others, even with mild warmth. Damage to autonomic nerves, which control sweating and blood flow, often causes this problem. When nerve damage disrupts sweating, you may sweat too much or not enough, which makes it hard to control your body temperature.

Common signs of heat intolerance include feeling unusually hot in warm rooms, sweating heavily or barely at all, and becoming dizzy or lightheaded in the heat. You may also feel nauseated, develop a headache during warm weather, or notice a rapid heartbeat when exposed to heat.

You may also struggle outdoors on sunny days, even when others feel comfortable. A short walk in warm weather can leave you drained. In severe cases, your body fails to cool itself properly, which can raise your core temperature quickly and lead to confusion, weakness, or fainting. Heat intolerance can affect daily life, especially in summer months or warm indoor spaces.

11. Bowel and Bladder Problems

Peripheral neuropathy can damage the nerves that control your bowel and bladder, which work automatically. When this happens, you may notice changes in how often you go or how well you can control it. Trouble emptying your bladder fully can make you feel like you still need to urinate right after you finish, and some people leak urine or lose control before reaching the bathroom.

Bowel changes are also common. You may deal with constipation because the muscles in your intestines move stool more slowly, while others may have loose stools or trouble controlling bowel movements.

These symptoms can develop slowly and may feel embarrassing, but they are linked to nerve damage, not personal failure. When nerves that control blood pressure and digestion are also involved, you may notice dizziness when standing or stomach discomfort along with bowel or bladder issues.

12. Changes in Blood Pressure

Peripheral neuropathy can damage the nerves that control automatic body functions, including blood pressure regulation. If these nerves do not work well, your blood pressure may not adjust the way it should. You may notice a sudden drop in blood pressure when you stand up, called orthostatic hypotension, which can make you feel lightheaded, weak, or dizzy within seconds of standing.

Some people feel faint or even pass out. You might also notice blurred vision, nausea, or a sense that the room is spinning. These symptoms often improve when you sit or lie down. Blood pressure changes can also cause unusual heart rate patterns, which leave you feeling shaky or tired.

These symptoms can increase your risk of falls, especially if they happen often. If you live with peripheral neuropathy, pay attention to how your body feels when you change positions. Blood pressure problems linked to nerve damage may develop slowly over time, and small changes can become more frequent as the condition progresses.

13. Paralysis

Paralysis can happen when nerve damage blocks signals between your brain and your muscles, which causes you to lose the ability to move part of your body. The weakness can start slowly or appear more quickly, depending on the cause. You might first notice trouble moving your toes, feet, fingers, or hands, and over time, the weakness can spread to other areas.

Peripheral neuropathy often affects the longest nerves in your body, so paralysis may begin in your feet or legs before moving upward. You may struggle to lift the front of your foot while walking, a problem called foot drop. Paralysis can affect one nerve or several nerves, which causes loss of movement in a small area or across both sides of your body.

Some infections, injuries, autoimmune conditions, and long-term diseases like diabetes can increase your risk. Treatment may include physical therapy and certain drug classes that reduce nerve inflammation or pain, but recovery depends on how much nerve damage has occurred.

14. Weak Immune Function

Peripheral neuropathy can link to health problems that weaken your immune system, which makes it harder for your body to fight off infections. You might get sick more often, and colds may last longer or wounds may heal slowly, especially if you also have diabetes. Nerve damage can also reduce feeling in your feet and hands, so you may not notice injuries right away, and a small blister or scrape can turn into a serious infection before you realize it.

Certain treatments for cancer, autoimmune diseases, or other long-term illnesses can both damage nerves and lower immune defenses, which reduces your body’s ability to fight bacteria and viruses. If you live with peripheral neuropathy, changes in your immune health can add to daily challenges.

15. Risk Factors

Several health conditions and lifestyle choices can increase your risk of developing peripheral neuropathy. Diabetes is the most common cause, as high blood sugar over time damages nerves in your feet and hands.

Physical injury, certain medications, age, and family history also play significant roles. Physical injury increases your risk because stretching, crushing, or cutting a nerve during an accident or surgery can prevent that nerve from working well afterward.

Certain cancer treatments, such as specific chemotherapy drugs, can damage nerves. Long-term use of some medications, including certain antibiotics, antiseizure drugs, and heart rhythm medicines, can also raise your risk.

Risk increases after age 55. Family history can play a role if inherited nerve disorders run in your family.

Lifestyle factors add to the risk. Smoking narrows blood vessels that supply your nerves. Poor diet and lack of physical activity can worsen other health problems that harm nerves over time.
