Why neuropathy feels worse at night
Peripheral neuropathy is a condition that never seems to follow the clock. Symptoms, like burning, tingling and numbness, can be constant, they can fluctuate based on activities, and sometimes there is no rhyme or reason. However, it is common that people notice their symptoms are much worse at night. Why is it that in the evenings when we are trying to relax and sleep, symptoms may get worse? Let’s break down some potential reasons.
The first factor that may contribute to increased symptoms involves your blood. Think of your blood vessels like highways carrying oxygen and nutrients to your nerves. During the day, you are upright and moving. Every step you take is like a little pump, helping the blood flow down into your legs. Movement keeps circulation following easier.
At night, it’s a different story. When you lie down, your muscles relax, and circulation slows. Imagine traffic at rush hour vs. at midnight; it’s not moving the same way. With reduced blood flow to the nerves, they are not getting the same oxygen and nutrients they may need. That lack of nutrients can make damaged nerves “scream” louder, which can cause symptoms to flare when you are at rest.
Another factor that may contribute to difficult nights involves the nervous system and distractions. During the day, you have plenty of distractions: work, chores, sounds of traffic or kids playing. Your brain is busy. At night, it’s quiet. With less distractions, your brain tunes in to signals it may ignore during the day. The damaged nerves may be sending faulty signals and now your brain has nothing else to focus on. What can that result in? Pain may feel sharper, tingling can be more irritating, and burning sensations may increase in intensity.
Lastly, the pressure factor may have influence on symptoms. When you lie flat, fluid naturally redistributes in your body. For someone who has nerve damage, even slight swelling in the feet or legs may put extra pressure on sensitive nerves. It’s like stepping on a garden hose; the water still flows, but it’s restricted and irregular. That “kink” in the system can create abnormal firing of the nerves. Abnormal firing often may lead to zapping or stabbing sensations at night.
Peripheral neuropathy is frustrating, especially when it robs you of sleep There are actions you can take that may lessen your symptoms at night, in case these factors are a part of your condition. Including gentle movements before bed like stretching or short walks, elevating your legs for 10-15 minutes, or a warm bath in your night time routine may reduce symptoms. Unfortunately, every condition is unique so this will not help everyone. The best recommendation I can give is to consult with a physician or professional on targeted care to improve your nerves.
