A.I. Health Assistant Causes for Knee Numbness

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced knee numbness. This list does not constitute medical advice.

  1. 1.Herniated (Slipped) Disk in the Lower Back

    The backbone, or spine, is made up of 26 bones called vertebrae. In between the bones are soft disks filled with a jelly-like substance. These disks cushion the vertebrae and keep them in place. Although people talk about a slipped disk, nothing actually slips out of place. The outer shell of the disk ruptures, and the jelly-like substance bulges out. It may be pressing on a nerve, which is what causes the pain.A slipped disk is more likely to happen due to strain on the back, such as during heavy lifting, and older individuals are at higher risk.

    The pain associated with a slipped disk usually goes away within six weeks. If the pain lasts longer, consult a doctor. They may send you to see a back specialist for an MRI of your spine, and surgery may be considered.

  3. 3.Chronic Idiopathic Peripheral Neuropathy

    Nerve damage in the limbs can be caused by diabetes, toxic substances, immune system issues and low vitamin levels. However, in about one of every four cases no cause can be found and then the condition is called 'idiopathic'. Symptoms of nerve damage can be (burning) pain sensations, numbness, tingling and weakness in hands, feet or lower legs.

    This is a chronic condition.
