Ganglion Cyst: Causes, Symptoms and Treatments
Ganglion cysts are fluid-filled lumps that often develop along tendons or joints. They can range from the size of a pea to the size of a golf ball and can be a cause of concern for many. These benign, non-cancerous growths commonly appear on the wrists, hands, ankles, or feet, and while they may not always cause pain, their presence can be bothersome and even restrictive.
This blog explores what ganglion cysts are, their causes, symptoms, and available treatment options. Whether you’re dealing with a ganglion cyst yourself or are simply curious about these common yet mysterious lumps, we’ll provide clear, helpful information to guide you through understanding and managing this condition.
The main symptom of a ganglion cyst is the presence of a lump that looks and feels smooth. They are made up of a thick, jelly-like fluid called synovial fluid, which surrounds joints and tendons to lubricate and cushion them during movement.
They are generally not painful and can be left alone to may disappear without treatment, although this can take several years. Occasionally they can feel firm to the touch and be uncomfortable, and if large enough the cyst can cause pressure upon a nerve within the wrist resulting in a tingling sensation, pain or numbness or a loss of mobility.
The exact cause of ganglion cysts is not clear, but they are thought to be related to injury, trauma, overuse or degenerative changes in the joint or tendon that lead to the overproduction of fluid, resulting in their formation. They are most common in:
Younger people between the ages of 15 and 40 and
Women are more likely to be affected than men.
Gymnasts - who repeatedly apply stress to the wrist.
It is worth noting that ganglion cysts that develop at the end joint of a finder on the nail side — also known as mucous cysts — are typically associated with arthritis in the finger joint and are more common in women between the ages of 40 and 70.
Treatment is usually only recommended if the cyst causes pain or affects the range of movement in a joint. The main treatment options for a ganglion cyst are:
Aspiration - draining fluid out of the cyst with a needle and syringe
Steroid injection - reduces inflammation and the risk of reoccurrence (post aspiration)
Surgery - cutting the cyst out
Aspiration and steroid injection are common treatments, providing a non-surgical option to alleviate discomfort and reduce cyst size. Using ultrasound guidance ensures accurate needle placement and avoids injuring important structures adjacent to the ganglion cyst. During aspiration, a needle is used to drain the fluid from the cyst, offering immediate relief, and is often followed by a steroid injection to reduce inflammation and prevent recurrence. While these procedures can be highly effective, it is important to note that cysts may return, necessitating further treatment.
While ganglion cysts are typically benign and often harmless, they can cause discomfort and interfere with daily activities. Understanding the causes, symptoms, and available treatment options, such as aspiration and steroid injections, can empower you to make informed decisions about your health. If you suspect you have a ganglion cyst or are experiencing persistent pain, do consult a healthcare professional to explore the best course of action.
We offer both aspiration and steroid injections here at the Leigh Injection Clinic based in Leigh on Sea, Essex. For more information please take a look at our website.
