The following symptoms and complaints may indicate orchitis (testicular inflammation):
Leading symptoms
- Edema (swelling) and redness of the testicle.
- Pain of the scrotum (scrotum) or testis radiating to the groin and back (increase on palpation/palping)
- High fever
- Chills
- Nausea (nausea)
- Fatigue
- Cephalgia (headache)
Usually, the inflammation occurs only unilaterally, that is, only one testicle is affected.
The Prehn’s sign is positive: the pain decreases when the testicle is raised, indicating orchitis (testicular inflammation) or epididymitis (epididymitis).
Mumps orchitis usually occurs after approximately five days after the onset of mumps symptoms. In up to 30% of cases, the symptoms of mumps orchitis are bilateral. Spontaneous improvement occurs after one to two weeks.
