In this case, it is a medical emergency . The rupture causes internal bleeding that can be serious without prompt treatment. The signs are often very pronounced:
Loss of consciousness.
Sudden difficulty speaking or moving one side of the body.
Sudden, intense and unusual pain.
When should you consult a doctor?
As soon as unusual, sudden and very strong pain appears.
In case of sudden neurological disorders : loss of vision, difficulty speaking, muscle weakness on one side of the body.
If a loved one is showing these symptoms, call 15 or 112 immediately.
