Causes:
Falls, being kicked by an opponent.
Symptoms:
Bleeding.
Important: if the injury has produced a large wound, you must consult a doctor immediately.
First Aid for smaller wounds:
First clean the whole area around the wound with clean linen cloth. The wound itself should be disinfected. Cover the wound using either a self adhesive plaster or sterile dressing. Change the dressing every day once the wound has closed, carefully rub on it a very thin layer of Traumeel ointment.
