Hands showing areas of numbness and painSymptoms may occur during the early stages of a MSD and are indicators that something is wrong or there might be a problem. Symptoms may occur anytime, not just at work. It is common for symptoms to occur sporadically, sometimes they are present and sometimes you feel fine.

Examples of symptoms include:

  • fatigue
  • aching
  • tingling
  • numbness
  • muscle tightness
  • cramping
  • burning sensation
  • pain

If you ignore these symptoms, signs of a MSD may occur.
