My grandmother developed this strange lump on her wrist overnight. What could this be? I am worried because it looks abnormal

Ganglion cysts typically present as a visible lump on the wrist or hand that may vary in size over time. These cysts are usually painless, but they can cause discomfort or pain if they press on nearby nerves or joints. The skin over the cyst may appear smooth, and the lump itself is often mobile beneath the skin.

In some cases, a ganglion cyst may restrict joint movement or cause a dull ache, particularly if it is located on the wrist. The size of the cyst can also fluctuate, sometimes becoming larger with increased physical activity involving the affected joint.

While ganglion cysts are a common cause of wrist lumps, other possibilities exist. These include lipomas, which are soft, fatty lumps that grow beneath the skin, and are usually harmless. Another possibility is a bone spur, which is a bony growth that can develop in joints due to arthritis or other degenerative conditions.

Other less common causes include rheumatoid nodules, which are firm lumps associated with rheumatoid arthritis, or infectious abscesses that result from bacterial infections. In rare cases, a wrist lump could be indicative of a more serious condition, such as a tumor, necessitating further examination and testing by a healthcare professional.

While many wrist lumps, such as ganglion cysts, are benign and not urgent, certain symptoms may signal a medical emergency. If the lump is accompanied by severe pain, redness, warmth, or fever, it could indicate an infection that requires immediate medical attention.

Additionally, if the lump is rapidly growing, causing significant pain, or affecting the function of the hand or wrist, it is important to seek prompt evaluation to rule out potentially serious conditions. Sudden loss of sensation or movement in the hand also warrants urgent medical assessment.

To diagnose a wrist lump, a doctor will typically begin with a physical examination, assessing the size, location, and characteristics of the lump. Imaging tests, such as an X-ray, ultrasound, or MRI, may be recommended to get a clearer view of the lump and its relation to surrounding structures.
