Causes of Numbness in the Feet
Sometimes your foot “goes to sleep” as the result of sitting awkwardly or wearing tight shoes. This is a temporary condition and in most cases, it resolves itself easily. Other causes of numbness in the feet and toes can be problematic as well as dangerous to your health. It can often be traced to a nerve damage that causes the feet to stop receiving transmissions from the brain, also known as peripheral neuropathy. Another common cause is damage to the circulatory system. Blood vessels become constricted and cannot supply the proper amount of blood to the area, causing peripheral artery disease (PAD). Diabetes, systemic diseases, vitamin deficiency, and alcoholism also can contribute to this condition. Physical conditions, including a herniated disc and spinal stenosis, can lead to numbness in one or both feet. Deep vein thrombosis (blood clots), extreme cold, atherosclerosis (a thickening of arterial walls), and Raynaud’s disease may cause numbness in the lower extremities. Caution is the byword when numbness, tingling and burning sensations in the feet and toes occur or won’t subside. Please consult a podiatrist as soon as possible for a diagnosis and appropriate treatment measures.
Neuropathy can be a potentially serious condition, especially if it is left undiagnosed. If you have any concerns that you may be experiencing nerve loss in your feet, consult with one of our podiatrists from Foot & Ankle Specialists of Nevada. Our Doctors will assess your condition and provide you with quality foot and ankle treatment for neuropathy.
What Is Neuropathy?
Neuropathy is a condition that leads to damage to the nerves in the body. Peripheral neuropathy, or neuropathy that affects your peripheral nervous system, usually occurs in the feet. Neuropathy can be triggered by a number of different causes. Such causes include diabetes, infections, cancers, disorders, and toxic substances.
Symptoms of Neuropathy Include:
- Sensation loss
- Prickling and tingling sensations
- Throbbing, freezing, burning pains
- Muscle weakness
Those with diabetes are at serious risk due to being unable to feel an ulcer on their feet. Diabetics usually also suffer from poor blood circulation. This can lead to the wound not healing, infections occurring, and the limb may have to be amputated.
To treat neuropathy in the foot, podiatrists will first diagnose the cause of the neuropathy. Figuring out the underlying cause of the neuropathy will allow the podiatrist to prescribe the best treatment, whether it be caused by diabetes, toxic substance exposure, infection, etc. If the nerve has not died, then it’s possible that sensation may be able to return to the foot.
Pain medication may be issued for pain. Electrical nerve stimulation can be used to stimulate nerves. If the neuropathy is caused from pressure on the nerves, then surgery may be necessary.
