Wrist Bumps: Possible Causes and Concerns

There is a bump on the wrist?

Hello Doctor, I have noticed that the area just below my thumb on my wrist has been occasionally painful and feels a bit swollen.
At first, I thought it might be a bone protrusion, but it doesn't quite feel like that.
After researching online, it seems similar to a ganglion cyst.
I would like to ask if this is considered a serious tumor, as the term "cyst" sounds quite alarming.
Is this condition not too serious, and should I not be overly worried? My family mentioned that someone had a similar issue but consulted a traditional Chinese medicine practitioner.
Also, could this be related to my frequent use of my phone or computer? I plan to make an appointment next week, but I am quite concerned and would appreciate your opinion.
Thank you.
The area I circled in the picture appears to have a noticeable bump.

Hello, this does appear to be a ganglion cyst, which is usually caused by accidental friction or injury.
It is benign and typically does not cause significant issues.
Some may gradually resolve on their own.
If it persists and you are concerned, you can consult a plastic surgeon's clinic.
Thank you for your inquiry.

More Info

Wrist bumps, particularly those located near the base of the thumb, can be concerning, especially when accompanied by pain. Based on your description, it sounds like you may be experiencing a ganglion cyst, which is a common condition. Ganglion cysts are non-cancerous lumps that often develop along the tendons or joints of your wrists or hands. They are filled with a jelly-like fluid and can vary in size. While they can be painful, especially if they press on nearby nerves, they are generally not harmful and are not classified as tumors.

The pain and bump you are experiencing could indeed be related to repetitive activities, such as frequent smartphone use or prolonged computer work. These activities can lead to strain on the wrist and surrounding structures, potentially contributing to the formation of a ganglion cyst or exacerbating existing conditions. Overuse injuries are common in individuals who engage in repetitive motions, and they can lead to inflammation and pain in the wrist area.

It’s important to note that while ganglion cysts are the most common cause of a bump in this area, other conditions could also be responsible. For instance, tenosynovitis, which is inflammation of the sheath surrounding a tendon, can cause pain and swelling. In some cases, a more serious condition, such as a tumor or a fracture, could be the underlying cause, although these are less common.

Regarding your concerns about the seriousness of the bump, it’s reassuring to know that ganglion cysts are benign. However, if the bump is causing significant discomfort or affecting your daily activities, it’s wise to seek medical attention. A healthcare professional can perform a physical examination and may recommend imaging studies, such as an ultrasound or MRI, to confirm the diagnosis and rule out other potential issues.

In terms of treatment, many ganglion cysts do not require intervention and may resolve on their own. If the cyst is painful or bothersome, options include aspiration (removing the fluid with a needle) or surgical removal. Physical therapy may also be beneficial, especially if your symptoms are related to repetitive strain.

In summary, while the bump you are experiencing is likely a ganglion cyst, it’s essential to consult with a healthcare provider for an accurate diagnosis and appropriate management. Your plan to see a doctor next week is a good step, and they will be able to provide you with the necessary guidance and treatment options. In the meantime, consider reducing activities that exacerbate your symptoms, such as prolonged phone or computer use, and apply ice to the area to help alleviate any discomfort.

Most tumors that appear as swelling on the left wrist are ganglion cysts, often caused by overuse of the wrist. Surgical excision or aspiration of the contents followed by corticosteroid injection can be performed, but if wrist overuse continues, recurrence may occur.
