If the lump appears suddenly after a significant injury, or you develop severe pain, deformity, or loss of sensation, seek urgent assessment as well.
These general warning signs follow guidance from the NHS on unexplained lumps and ganglion cysts. <Cite refs={[“turn292722search0″,”turn292722search1”]} />
- What You Should—and Shouldn’t—Do at Home
While waiting for an appointment, avoid repeatedly pressing, squeezing, or attempting to drain the lump. This can irritate the surrounding tissue and may cause injury or infection.
If the swelling followed a minor injury, resting the affected hand and protecting it from activities that worsen the pain may help. Do not force a stiff finger to move or apply tight wraps that cause tingling, discoloration, or increased pain.
You can take a photograph and note the lump’s approximate size and location. Recording when it appeared and whether it changes over time can help a healthcare professional understand what is happening.
