The feeling will come on gradually and may start to spread from your hands and feet up through your arms and legs. If your numbness, prickling, or tingling sensations do not have an obvious cause, such as sitting on your leg for too long or sleeping funny, you should talk to your healthcare provider.  If your feet are numb, it can change the way that you walk. Over time, the change can affect your body in other ways, such as causing foot deformities or pain from an uneven gait. You may also get blisters and sores around the affected areas of your feet because you cannot feel that you are walking unevenly. You may experience sharp, jabbing, throbbing, burning, or freezing pain caused from issues within your nerves and not due to an injury. If you’re experiencing pain for no reason, it could be neuropathy. Since your nerves are not responding properly to sensations, you may feel sensations more strongly than you did before. Although this is rare, it could mean that a light pat on the back feels painful to you, or that a hug ignites your pain receptors. If this is caused by neuropathy, it will likely be a recent development and not a lifelong issue with clumsiness. Consider if you’ve been bumping into doors and furniture more often lately, or if you’ve suddenly started to fall down or trip for seemingly no reason. When your motor nerves are affected by the neuropathy, you’ll experience muscle weakness and possibly paralysis because the nerve can’t appropriately communicate with your muscles. In late stages of neuropathy, you may have trouble moving around, picking things up, or even talking. If your autonomic nerves are affected, you may have trouble regulating your bodily functions. This includes telling your body to sweat when you get hot. Your body may not sweat as often, causing you to overheat. Though these symptoms alone could be caused by a variety of problems, if you have them in conjunction with other symptoms like numbness or pain, they may indicate neuropathy. Neuropathy causes nerve damage, so your nerves may not be able to send messages to your body to tell it when to go to the bathroom, when to process food, and when to stop those functions. It’s possible that you may experience the following symptoms:  Constipation Diarrhea Nausea Vomiting Indigestion Problems urinating Erectile dysfunction in men Lack of vaginal fluid in women If you have neuropathy, your body may be unable to regulate your heart rate and blood pressure, so it won’t be able to respond to changes in your activity levels. Your heart rate may remain high even when you are not exercising, and your blood pressure can quickly drop, causing you to feel dizzy. If you have dizziness or lightheadedness along with pain or tingling, it could be neuropathy. The dizziness and lightheadedness may be worse when you sit down or stand up.
Watch for numbness, prickling, or tingling in your hands or feet. Notice if you have pain with no direct external cause. Consider if you have extreme sensitivity to touch. Look for a lack of coordination and a tendency to fall down. Notice muscle weakness and paralysis. Consider if you’ve become heat intolerant or are sweating less. Look for bowel, bladder, or digestive issues. Watch for dizziness and lightheadedness.
