Causes of Peripheral Neuropathy in the Feet
Peripheral neuropathy in the feet can be caused by various factors. The most common cause is diabetes, which affects a large number of people worldwide. Additionally, there are other potential causes such as hereditary disorders, arthritis, autoimmune conditions, viral infections like shingles, injuries, and certain neurological conditions including fibromyalgia and spina bifida.
Furthermore, some chemotherapy drugs and medications have been known to cause damage to the peripheral nerves, leading to neuropathy. Excessive alcohol consumption is also a risk factor for nerve damage in the feet. It is important to note that the risk of developing peripheral neuropathy increases with age.
Complications of Neuropathy in the Feet
Neuropathy in the feet can give rise to various additional medical complications. When an individual is affected by peripheral neuropathy, they may inadvertently step on sharp objects or walk with a stone in their shoe without feeling any discomfort since the nerves in their feet fail to transmit pain signals. The accompanying numbness also makes it difficult to perceive friction from socks or shoes, increasing the risk of developing blisters.
Since these injuries often go unnoticed, cuts and blisters are left unprotected and untreated, allowing them to worsen over time. This creates an ideal environment for infections to take hold and further exacerbate the condition.
