A course of antibiotics will normally be prescribed once epididymo-orchitis has been diagnosed. The type of antibiotic will depend on the underlying cause of the infection.
Once antibiotics have been started, pain normally improves within a few days. However, swelling may take a few weeks to completely go down.
If an STI is the cause, don’t have sex until treatment and follow-up are completed. Sexual partners may also need antibiotics.
Antibiotics do not kill viruses so are not needed if the cause is viral, such as mumps.
