Tingling or numbness affecting your feet may seem like a trivial symptom of no real importance. However, in this tutorial, I will explain why this symptom may be very important with regard to your health in general and why you should not ignore it. Tingling hands, feet, or hands and feet is an extremely common and bothersome symptom. Such tingling can sometimes be entirely innocent and temporary. For example, it could result from pressure on nerves when your arm is bent under your head as you fall asleep. Or it.
Could be from pressure on nerves when you cross your legs for too long. in either case, the pins and needles effect which is usually painless is soon relieved by removing the pressure that caused it. In many cases, however, tingling in the hands, feet can be severe, occurring at irregular times or continuously day and night. It also can accompany other symptoms. such as pain,itching, numbness, and muscle wasting. In such cases, tingling may be a sign ofnerve damage.
Suchnerve damageis known by s asperipheral neuropathybecause it affects nerves distant from thebrainand spinal cord, often in the hands and feet. There are more than 100 different types of peripheral neuropathy. Over time, peripheral neuropathy can worsen, resulting in decreased mobility and even disability. In fact, diabetesis the number one cause of peripheral neuropathy, accounting for well over a third of cases. Indiabetic neuropathy, tingling and other symptoms often first develop.
In both feet and go up the legs, followed by tingling and other symptoms that affect both hands and go up the arms. About twothirds of people with diabetes have mild to severe forms ofnerve damage. In many cases, these symptoms are the firstsigns of diabetes. So here is the main point I want to make, tingling and numbness in the feet may be the first signs that you have a serious peripheral neuropathy and that you may have diabetes. Diabetes puts you at risk of heart attack, stroke, kidney failure, blindness and a long.
List of other serious complications. so that tingling you have could be your only warning sign of a serious complication developing elsewhere in your body. Dont ignore this symptom and please get a check up. Well I hope you have found this tutorial interesting. Do please remember to subscribe and that way you will be the first to see my next tutorial on leg health and venous disease. My name is Haroun Gajraj, thank you for watching.
Why Cant We Reverse Nerve Damage
Every year, tens of millions of americans suffer from nerve damage, some irreparably so. Science can heal bones, grow new organs and even restore our microbiomes, but why is it so hard to fix our nerves? Hey guys Lissette here for DNews The human body posses a remarkable ability to heal. Bones refuse, skin wounds mend, and the immune system adapts to infection, after infection. But theres one area of.
The body that struggles to recover after an injury: the nervous system. nerve damage can be some of the most debilitating and permanent type of injury. The nervous system is an incredibly complex network used to send electrical information throughout your body. It can basically be divided into two sections. With the brain and spinal cord making up the central nervous system or CNS. and the nerves made up of fibers of sensory and motor neurons comprising the peripheral nervous system.
Each cell in the nervous system from the tip of your finger up your arm, up your spinal column, into your brain, is very specialized. And each has a unique function on the pathway, like a circuit. If one these gets cut or injured, its hard for an exact replacement cell to be put in in the right spot. Think about when you get a cut on your skin. If the cut goes deep enough, exact replicas of cells won’t cover the wound, instead fibrous tissues form. which we call scars. And scars are part of the problem in regrowing nerves, they.
Often get in the way especially in the case of spinal cord injuries. as part of the cns, spinal cord injuries are notoriously difficult to heal; partially because of the way nerve cells in the CNS are made. According to the book, Results and Problems in Cell Differentiation, the CNS also has certain proteins that weirdly, inhibit cell regeneration. While this might sound like a bad idea, its hugely beneficial overall to the formation of the CNS. These cells need.
To grow exactly where they are supposed to, just one out of place could be bad. like. think of an electrical circuit, each unit has to be in a specific order in specific place to work. If one is out of place, the integrity of the CNS is compromised. Neurons in the CNS also lack certain cleaning cells. Nerve cells are made up of many parts, but they send signals through threads covered in a protective sheet of myelin. These threads are called axons. Axons are the long part of the cell that reaches out to the cell next.
To it to send information down the line. like arms handing the bucket down the line in a bucket brigade. So these are obviously super important and need protecting. Thats where the Schwann cells come in. which are only found in the Peripheral nervous system. Schwann cells, which arent neurons but GLEEL cells, produce the myelin that help protect the axons. But, a study published in The Journal of Cell Biology found they also clean up damaged nerves making way for the healing process to take place and.
New nerves to be formed. but the problem is. these schwann cells are missing from the cns. What they have instead are myelin producing cells called oligodendrocytes. But these cells dont clean up damaged nerve cells at all. Which is part of the problem. So unfortunately, according to Richard G. Fessler professor at Rush University Medical Center There are currently no therapies which successfully reverse the damage from injuries to the spinal cord. But research is currently underway to examine the potential success.
Of stem cell treatment, where stem cells are injected directly at the injury site. still, it will take a few years to see the results of such trials. But there are times your body can regenerate nerves. The peripheral nervous system doesnt have the same blocking proteins that the CNS has, and Schwann cells help heal the damage. So its able to regrow nerves, albeit slowly. For instance, if you cut a nerve into your shoulder, it could take a year to regrow. By that time.the muscles in your arms could.
