Ganglion Cysts are benign (non-cancerous) soft tissue lumps that can appear either slowly or fairly quickly.
They generally have an outer casing with a thick, gel like content (mucin) and are formed by the gel leaking from a tendon sheath or joint.
Typically they do not cause pain, although when they appear around the foot and ankle they can become irritated by footwear.

If you suspect you have a Ganglion Cyst you should seek referral to a Podiatrist. For the NHS Podiatry service this may be through your GP, another health professional or by calling 029 2033 5135 for a self-referral form.
Please make sure your Podiatrist is registered with the Health and Care Professions Council and look out for the letters HCPC after their name.
