When to see a doctor

Seek professional care if you experience any of the following symptoms

  • Numb arm

Possible causes

  • osteoporosis

    Osteoporosis is a disease that makes your bones weak and brittle, resulting in the bone to fracture easily even with minor trauma or stress (for instance, after a simple fall). It may be caused due to long-term low calcium intake, estrogen deficiencies in women, and an inactive lifestyle.

  • Neuropathic pain

    Neuropathic pain is usually caused by an injury, disease, or problem with the somatosensory nervous system. This is a common long-term pain condition that greatly affects a person's quality of life. The nerves in this system are what let us feel things like temperature, pressure, and pain. This type of pain often feels like a burning, tingling, sharp, or stabbing sensation. It can be triggered by light touch or cold, and can be constant or come and go. It can also get worse when resting or at night. Neuropathic pain is often caused by viral infections like post-herpetic neuralgia, cancer, blood vessel abnormalities, alcoholism, diabetes, nerve pressure, nerve damage from surgery or accidents, and neurological conditions like multiple sclerosis and shingles.

  • Chronic pain

    Pain that is ongoing and typically lasts longer than six months. This kind of pain can persist even after the injury or illness causing it has healed or disappeared. It interferes with daily life and can lead to depression and anxiety.

  • Diabetic neuropathy
  • Rheumatoid arthritis (RA)
  • Thoracic outlet syndrome
  • Cervical spondylosis

Related serious diseases

  • Cerebral infarction

    Cerebral infarction refers to damage to brain tissue resulting from a stroke. It occurs due to decreased blood supply and oxygen delivery to the brain, causing brain cell death and brain damage. It is typically caused by a blood clot or fatty/cholesterol plaques blocking a blood vessel to the brain, but can also occur if a blood vessel ruptures and bleeds into the brain.

  • Hypocalcemia
  • Hyperkalemia
