  1. 1.Morton Neuroma

    Morton neuroma is nerve damage between the 2nd and 3rd toes, often found in women who run or wear tight high heels.

    Almost all patients do well with conservative (non-surgical) treatment

    Urgency:
    Self-treatment
  2. 2.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.

    Rarity:

  3. 3.Low Calcium Level

    Hypocalcemia is a condition where there is not enough calcium in the blood. Calcium is a mineral contained in the blood, which helps the heart and other muscles function properly, and is needed to maintain strong teeth and bones.

    Problem should go away with home care within weeks.

    Top Symptoms:

  4. 4.Folate (Vitamin) Deficiency

    Folic acid (folate) is a vitamin that is needed to make new cells in the body, including red blood cells which carry oxygen through the blood and into various tissues throughout the body. Folate deficiency refers to a condition when there is not enough folic acid in the body, and can lead to symptoms such as tiredness, low energy, faintness, and difficulty breathing.

    People recover with no long-term effects within weeks.

  5. 5.Vertebral Osteomyelitis

    Infection of the spinal bones (Vertebral Osteomyelitis) is caused by the spread of bacteria through the blood from another body part that lands in the spine. It's typically caused by bugs named Staph. Aureus (40-50% of the time), streptococci (12%), e.coli (9%), and Pseudomonas aeruginosa (6%).

    6 weeks of antibiotics typically clears things up

    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.

  10. 10.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
