Three Types Of Peripheral Neuropathy

Treating Numbness Tingling and Burning Caused by Neuropathy

My name is David Northcutt. I'm oneof the podiatrists here at Dallas Podiatry Works. Today I want to discuss diabetic peripheralneuropathy. There are several reasons for the development of peripheral neuropathy,but diabetic peripheral neuropathy is one of the most common. Diabetic peripheral neuropathy simply meansnerve damage that is caused from having diabetes. This is not something that develops rapidly,but is a slowly worsening and progressive condition which happens over the period ofseveral years. The loss of sensation that occurs with nerve damage from diabetes makesthe patient more prone to developing open

sores or ulcers. Patients often do not know that they havea sore or wound, due to this lack of sensation. This can lead to significant complicationsincluding amputations. Diabetic peripheral neuropathy usually occurs in patients whodo not maintain their blood sugar well, however it can occur in anyone with diabetes. The symptoms of neuropathy include numbness,tingling, pain, burning in the feet which can progress up to the legs, there's oftenloss of muscle tone, loss of balance, and changes to foot structure. To determine whetheryou have diabetic peripheral neuropathy, a

history and physical will be performed. Simple,in office, noninvasive testing helps to diagnose the problem. Neurologic tests sometimes areordered. Sometimes a biopsy of the peripheral nerves in the skin may also be performed.Treatment of diabetic peripheral neuropathy begins with good control of your blood sugar.There are oral medications as well as topical medications that may reduce your symptoms.Prevention of diabetic peripheral neuropathy includes maintaining good blood sugar levels. If you have any symptoms of numbness, burning,tingling in your feet or legs, please give us a call at Dallas Podiatry Works. We willwork to get the correct diagnosis to help

relieve your symptoms.

Peripheral Nervous System Crash Course AP 12

When it comes to the nervous system, or justyour body in general, let's face it: your brain gets all the props. And it deserves those props! It's a complicated,and crucial, and sometimes crazy boss of an organ. But your brain would be pretty useless withouta support team that kept it connected to the outside world. Because frankly, like any leader, the moreisolated your brain gets, the weirder it gets. Put a person in a watery, pitchblack sensorydeprivation tank, and you'll see the brain do some really weird stuff. Without a constantflood of external information, the brain starts

to confuse its own thoughts for actual experiences,leading you to hallucinate the taste of cheeseburgers, or the sound of a choir singing, or the sightof pink stampeding elephants. It's your peripheral nervous system thatkeeps things real, by putting your brain in touch with the physical environment around you,and allowing it to respond. This network snakes through just about every part of your body,providing the central nervous system with information ranging from the temperature, to the touchof a hand on your shoulder, to a twisted ankle. The peripheral nervous system's sensorynerve receptors spy on the world for the central nervous system, and each type responds todifferent kinds of stimuli.

Thermoreceptors respond to changes in temperature.photoreceptors react to light, chemoreceptors pay attention to chemicals, and mechanoreceptorsrespond to pressure, touch, and vibration. And then we've got specialized nerve receptorscalled nociceptors that, unlike those other receptors, fire only to indicate pain, whichis the main thing I want to talk about today. Because, as unpleasant as a stick in the eyeor tack in the foot may be, pain is actually a great example of where everything we've talkedabout over the last few weeks all comes together, as we trace a pain signal through your nervoussystem, from the first cuss to the Hello Kitty band aid. By the end of this episode of Crash CourseAnatomy Physiology you'll never think

of a stubbed toe, pounding headache, or burnedtongue the same way again. Most people go to great lengths to avoid pain,but really, it's an incredibly useful sensation, because it helps protect us from ourselves,and from the outside world. If you're feeling physical pain, it probablymeans that your body is under stress, damaged, or in danger, and your nervous system is sendinga cease and desist signal to stop twisting your arm like that, or to back away from that bonfire,or please seek medical attention, like, RIGHT NOW. So in that way, pain is actually good foryou that's why it exists. I'm not saying it's pleasant, but if you've ever wishedfor an XMenlike power to be impervious to

pain, I've gotta say, that is one foolishmonkey's paw of a wish. Just ask Ashlyn Blocker. She's got a geneticmutation that's given her a total insensitivity to any kind of pain. And as a result, she'sabsentmindedly dunked her hands in pots of boiling water, run around for days without noticingbroken bones, and nearly chewed off her own tongue. Luckily, such congenital conditions are veryrare. The rest of us have a whole nervous system dedicated to making sure our bodies react witha predictable chain of events at the first sign of damage. Like say you just wake up and you're extraordinarilyhungry for some reason, so you run downstairs to grab some clam chowder, but you didn't putany shoes on and suddenly you're like, “YOWW!�

There's a tack, fell out of the wall, andyou stepped right on it of course. Your foot immediately lifts off the ground,and then you're assuring your dog that you're not yelling at her, you're just yelling,and then you limp over to the couch, and sit down, and you pull up your foot, and removethat spiny devil from your flesh. You want to talk physiology? So what exactlyjust happened in your body? Well, the first step was a change in yourenvironment that is, a stimulus that activated some of your sensory receptors. In this case, it was a change from the probablycompletely ignored feeling of bare skin on
