A.I. Health Assistant Causes for Numbness in One Foot

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

  1. 1.Sciatica

    The sciatic nerve is the largest nerve of the human body, and it runs through the buttock, down the thigh and into the calf, sending information to the muscles in the back of the thigh and leg, as well as the surrounding skin. The sciatic nerve itself is supplied by nerves coming from the spine in the lower back. Sometimes, one of the disks separating the vertebrae (bones of the spine) may bulge out a little bit, putting pressure on one of these nerve roots, causing sciatica, or shooting pain down the sciatic nerve.

    Problem will resolve itself within several weeks in 80-90% of cases.

    Rarity:
    Common
    Top Symptoms:
    back pain, back pain that shoots down the leg, numbness in one foot, pain in one leg, numbness in one thigh

  2. 2.Tarsal Tunnel Syndrome

    The tarsal tunnel is a narrow space that lies on the inside of the ankle next to the ankle bones. Tarsal tunnel syndrome is a compression, or squeezing, on an important nerve called the posterior tibial nerve. This compression produces symptoms anywhere along the path of the nerve running from the inside of the ankle into the foot.

    Tarsal tunnel syndrome is a long-term condition that may need to be managed for months up to 1-2 years.
