Ganglions - Causes

The exact cause as to why ganglions occur is still not known. The origin and how it occurs can be explained as-

  • A special viscous liquid is sealed in a small compartment and lubricates the joints and tendons.
  • Sometimes,fornoknown reason or due to arthritis oraninjury,the compartment might leak this liquid.
  • The liquid is viscous and thick, like honey, and the leaking hole is usually too small. Once it leaks it doesn't go back on its own.
  • This works almost like a one-way valve, filling up like a little balloon next to the area of the leak.
  • When the hands are used for normal activities, the joints squeeze and create a tremendous pressure in the lubricating compartment, which can cause enough pressure in the leaking cyst and can feel as hard as a bone.
  • This lubricating liquid has special proteins, which makes it thick, and also makes it hard for the body to absorb it when it leaks out.
