- A painless testicular lump is not something to ignore.
- Sudden severe testicular pain can be torsion and is time-sensitive.
- Fever, urinary symptoms or discharge may point toward infection but still require assessment.
Why this deserves attention
A lump or swelling in the scrotum can come from cysts, fluid collections, enlarged veins, infection, hernia or a testicular tumour. The person cannot reliably distinguish these by touch alone. A new lump within the testicle deserves medical assessment even if it is painless.
What makes it more important
Note whether the change is in the testicle itself or around it, whether it appeared suddenly and whether there was injury. Ultrasound is often useful for distinguishing different causes.
What to do next
Do not repeatedly squeeze a lump to see whether it changes. Arrange medical review promptly; embarrassment should not create months of delay.
Where TCM may fit
TCM massage, topical medicines or strong heat should not be applied to a new unexplained testicular lump before diagnosis.
When not to wait
Sudden severe testicular pain, especially with nausea/vomiting or a high-riding testicle, requires emergency assessment because torsion can threaten the testicle.
