Causes of Neuropathic Pain
Neuropathic pain differs from other types of pains and in order to start talking about neuropathic pain, it’s important to remember what pain actually is. So, nociceptive pain or pain that we sense usually is nerves transmitting an impulse and letting us know that there is a damage or injury to part of our body. Neuropathic pain is an actual pathology of the nerve itself. Nerve consists of its body, which is the axon, which is the part that usually gets injured and when that axon is injured what happens is abnormal transmission of impulses. It’s important to remember that it’s not nerves communicating an injury elsewhere, but the process in the nerves themselves. Neuropathic pain itself presents differently.
From other types of pain. So, neuropathic pain is likely to be severe. It is usually sharp. It is electric shocklike sensation that people usually describe. It is lightning or lancinating type of pain that most people talk about when they describe neuropathic type of pain. Accompanying that, it can be a deep burning or, at the same time, it can also present as coldness in the limbs or distribution of that nerve. It also comes, at times, with persistent numbness, tingling, or weakness of the muscles that nerve supplies. Neuropathic pain usually travels along the path of the nerve itself. Because the nerves have different function some nerves are motor nerves, some nerves are sensory nerves.
if the sensory part of the nerve is affected, it can alter sensation. Now, it can actually decrease sensation in other words, create numbness or it can heighten sensation where normal stimuli are now painful or altered so something that would usually be a normal muscle sensation, such as light touch, can become a painful sensation. There are many causes for neuropathy or neuropathic pain affecting the nerves. Some of those are compression of the nerve. Now, compression of the nerve can occur anywhere along the path of the nerve. It can be as it exits the spine and travels onward, as in radiculopathy or in other words, pain arising from compression of the spinal nerve before it exits the spinal.
Column or it can be peripheral nerve compression. And many of us know what it feels like when we cross our legs and the leg goes numb that is compression of the peripheral nerve and usually that recovers by itself, but if that compression remains for a longer period of time, then that can become not necessarily permanent, but the recovery from that can take months and sometimes even a whole year. Other sources of the neuropathy can be systemic processes, such as diabetes. Diabetes is a microvascular process decreasing the supply of nutrients to tissues as well as nerves and that tends to be what’s called a quot;lengthdependant process,quot; in other words, nerves that are longer tend to be affected first and that’s.
Why people with diabetic neuropathy tend to feel their feet being affected first because the nerves are that much longer, so those nerves tend to be affected first, then the hands follow that because they are the next longest nerves in the body. That being said, any process that can damage tissue can also damage nerve tissue. So, what I mean is treatments like chemotherapy there are different chemotherapy agents that can alter different processes that the nerves depend on and some are actually neurotoxic in other words, they are damaging the nerves directly. Now, chemotherapy affecting the nerves can appear at the time of the treatment, but it can also be a delayed presentation.
Of that neuropathy. Also, radiation; a process that radiation causes, in the long run, can come up as postradiation fibrosis. In other words, tissues fibrose and contract and can affect the nerves and that can cause neuropathy as well.
Treating Numbness Tingling and Burning Caused by Neuropathy
My name is David Northcutt. I’m one of the podiatrists here at Dallas Podiatry Works. Today I want to discuss diabetic peripheral neuropathy. There are several reasons for the development of peripheral neuropathy, but diabetic peripheral neuropathy is one of the most common. Diabetic peripheral neuropathy simply means nerve 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 of several years. The loss of sensation that occurs with nerve damage from diabetes makes the patient more prone to developing open.
Sores or ulcers. Patients often do not know that they have a sore or wound, due to this lack of sensation. This can lead to significant complications including amputations. Diabetic peripheral neuropathy usually occurs in patients who do 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 often loss of muscle tone, loss of balance, and changes to foot structure. To determine whether you have diabetic peripheral neuropathy, a.
History and physical will be performed. Simple, in office, noninvasive testing helps to diagnose the problem. Neurologic tests sometimes are ordered. 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 will work to get the correct diagnosis to help.
